noreply@blogger.com (Unknown) — Tue, 14 May 2024 23:25:00 +0000

Cancer is a frightening and complex illness that impacts the lives of numerous individuals across the globe. In the past few years, remarkable progress has been achieved in diagnosing and treating cancer, largely due to the creation of comprehensive cancer profiling methods. One such method involves using immunofluorescence (IF) assays to identify specific cancer biomarkers, like HER2 and ER, in blood samples. Measuring HER2 and ER levels with IF assays help doctors determine the cancer subtype, diagnosis, and best treatment approach. However, the precision and dependability of these assays heavily rely on the software programs used to examine and interpret the results. This is where software testing becomes critical.

Understanding Comprehensive Cancer Profiling

Comprehensive cancer profiling is an innovative strategy for diagnosing and treating cancer that entails examining a patient's cancer at the molecular level. By pinpointing specific genetic changes, protein expression patterns, and other biomarkers, physicians can acquire a more thorough understanding of a patient's unique cancer and customize treatment accordingly.

One of the most encouraging methods for comprehensive cancer profiling is the use of IF assays to identify cancer biomarkers in blood samples. IF assays employ fluorescently labeled antibodies that attach to specific proteins or other molecules in a sample, enabling them to be visualized and measured under a microscope. By assessing the levels of certain biomarkers, such as HER2 and ER, doctors can establish the subtype and aggressiveness of a patient's cancer and choose the most suitable treatment options. To make it simple, imagine you have a special flashlight that only shines on a specific type of object, like a particular toy in a messy room. In this case, the flashlight is the fluorescently labeled antibody, and the toy is the protein or molecule you want to find in a sample, like a piece of tissue or a group of cells.

The Crucial Role of Software Testing

Although IF assays have the potential to transform cancer diagnosis and treatment, their precision and reliability depend on the software applications used to analyze and interpret the results. These applications must be capable of accurately detecting and quantifying the fluorescent signals produced by the assay, distinguishing true positive results from background noise, and generating consistent and reproducible results across various samples and assay runs. This is where software testing becomes essential.

There are several key areas where software testing helps enhance the precision and reliability of IF assays for cancer profiling:

1. Assay Validation

Before an IF assay can be utilized for clinical decision-making, it must undergo extensive validation to ensure its accuracy, precision, and reproducibility. Software testing plays a vital role in this validation process by verifying that the assay software is correctly detecting and quantifying the fluorescent signals generated by the assay. This is accomplished by testing the software with a range of known positive and negative control samples. Testing with these controls helps guarantee that the software can accurately differentiate between true positive and true negative results. It also involves testing the software's ability to produce consistent results across different assay runs and operators.

2. Image Analysis

IF assays generate intricate images of fluorescently labeled cells that must be analyzed by specialized software to extract meaningful data. Software testing is crucial for ensuring that the image analysis algorithms are correctly identifying and quantifying the relevant fluorescent signals while minimizing background noise and artifacts. For testing the software is put through a series of tests using a diverse set of images to ensure that it can correctly analyze the fluorescent signals, identify different cell types, and generate consistent and reliable data, even when the quality of the images may vary due to factors related to sample preparation or image acquisition.

3. Data Management

IF assays generate vast amounts of complex data that must be securely stored, managed, and analyzed to generate clinically meaningful results. Testing becomes critical for ensuring that the data management systems are reliable, efficient, and compliant with relevant regulations and standards. This is achieved by testing the software's ability to securely store and retrieve data, maintain data integrity and traceability, and generate accurate and complete reports. It also involves testing the software's performance and scalability to ensure that it can handle large volumes of data without compromising speed or accuracy. There are various COTS products available to achieve the goals listed above.

4. Clinical Decision Support

The goal of comprehensive cancer profiling using IF assays is to provide pathologists with actionable information to guide treatment decisions. Software testing is essential for ensuring that the clinical decision support systems are accurately interpreting the assay results and providing reliable and evidence-based recommendations. The process includes testing of software's ability to integrate data from multiple assays and other clinical sources, apply complex algorithms and decision rules, and generate clear and concise reports that highlight the most relevant findings and recommendations. It also involves testing the software's usability and user interface to ensure that lab technicians can easily access and interpret the results.

Bottom Line

As cancer profiling techniques continue to advance and become more complex, the role of software testing will only become more important. By collaborating closely with assay developers, clinicians, and researchers, software testers can help ensure that these powerful tools are used safely and effectively to improve the lives of cancer patients. This can lead to better patient outcomes, lower healthcare costs, faster drug development, and improved research insights.

Glossary:

Biomarkers are measurable indicators of the severity or presence of some disease state. In cancer, biomarkers can include proteins, genes, or other molecules that provide information about the cancer's behavior, prognosis, and response to therapy.
An assay refers to a laboratory procedure or test used to detect, measure, and analyze specific molecules or biological markers in a sample.
IF assays use fluorescent dyes to label and detect these biomarkers in tissue or blood samples. Two important biomarkers in breast cancer are HER2 and ER:
- HER2 (human epidermal growth factor receptor 2) is a protein that promotes the growth of cancer cells. Cancers with high levels of HER2 tend to be more aggressive.
- ER (estrogen receptor) is a protein that binds to the hormone estrogen and helps the cancer grow. Cancers with ER are called "ER-positive" and can be treated with hormone therapy drugs.
Positive controls contain the biomarker being tested and should always give a positive result. They ensure the assay is working properly.
Negative controls do not contain the biomarker and should always give a negative result. They check for any background noise or false positive signals.
Operators refer to the individuals or technicians who are running the assay and using the software to analyze the results. When validating an assay and its associated software, it is important to ensure that the results are consistent and reproducible, not only across different assay runs but also when different operators are using the system.

noreply@blogger.com (Unknown) — Sat, 30 Mar 2024 18:39:00 +0000

Data poisoning has recently gained significant attention in the news due to its negative impact on machine learning (ML) and artificial intelligence (AI) systems. However, data poisoning is not a new phenomenon and has been a concern in various domains, including software testing. In the context of software testing, data poisoning refers to the deliberate manipulation or contamination of data used in the testing process, with the aim of compromising the accuracy and effectiveness of the tests.

For example, consider a scenario where a malicious actor intentionally modifies the input data used in a software's login functionality test cases. They may introduce invalid or edge case inputs, such as extremely long usernames or passwords containing special characters, to test the system's resilience against unexpected or malicious inputs. Another example could be the manipulation of test environment variables, such as changing the database connection string to point to a corrupted or tampered database, leading to incorrect test results and potentially hiding critical defects.

What is Data Poisoning?

Data poisoning involves introducing malicious, misleading, or incorrect data into the testing dataset to disrupt the testing process and produce misleading results. It can occur at various stages of the testing lifecycle, from test case generation to test execution and result analysis. There are several types of data poisoning that can affect software testing:

Input Manipulation: This involves modifying the input data used in test cases to introduce edge cases, invalid inputs, or malformed data. The goal is to test the software's ability to handle unexpected or malicious inputs gracefully.
Test Data Corruption: In this type of data poisoning, the test data itself is corrupted or tampered with. This can include modifying existing test data, injecting false data, or deleting critical data points. The aim is to disrupt the testing process and produce misleading results.
Test Environment Manipulation: Data poisoning can also target the test environment by altering configuration settings, modifying environment variables, or introducing external dependencies that affect the behavior of the software under test.
Result Manipulation: In some cases, data poisoning may involve tampering with the test results themselves. This can include modifying log files, altering test reports, or manipulating the pass/fail criteria to hide defects or falsely indicate successful test runs.

Impact of Data Poisoning on Software Testing

Data poisoning can have severe consequences on the software testing process and the overall quality of the software being developed. Some of the key impacts include:

False Positives and False Negatives: Poisoned data can lead to incorrect test results, causing false positives (tests passing when they should fail) or false negatives (tests failing when they should pass). This can mislead testers and developers, leading to the release of software with hidden defects or the unnecessary allocation of resources to fix non-existent issues.
Reduced Test Coverage: Data poisoning can affect the thoroughness of the testing process by limiting the scope of test cases or skipping critical test scenarios. This can result in inadequate test coverage, leaving portions of the software untested and potentially harboring defects.

Recipe for Disaster: The 'Don'ts' of Bug Reporting with a Dash of Humor

noreply@blogger.com (Unknown) — Wed, 21 Feb 2024 17:40:00 +0000

Welcome to the quirky kitchen of bug reporting, where the secret sauce is in the details and the main ingredient is clarity. Let's ensure your bug report isn't the equivalent of unseasoned dal—bland and unhelpful.

Vague Descriptions: The "Something's Wrong" Syndrome

Ever stumbled upon a bug report that simply states, "It's kaput"? That's as helpful as a chef shouting, "It's not tasty!" in the middle of a bustling kitchen. What's not tasty? The soup? The curry? A good bug report should be like a well-written recipe, with every ingredient and step laid out for a perfect replication of the dish—or in this case, the bug.

The Dance of Reproduction Steps

Trying to fix a bug without reproduction steps is like trying to bake a cake without a recipe. Developers need the full list of ingredients and the baking time to whip up a solution. The more precise your steps, the less likely they'll end up with a deflated cake—or an unfixed bug.

The Environment Puzzle

Saying a bug occurred "on my computer" is as vague as a food critic saying a dish was "good." Was it the spices? The texture? Similarly, was the bug on Windows, macOS, or Linux? Bugs can be finicky eaters, feasting on some systems while ignoring others. Provide a full menu of the environment details to help developers serve up a fix.

Clear Communication: Avoiding the Grammar Gremlins

A bug report with typos and grammatical errors is like a recipe with missing steps. Will your soufflé rise to the occasion, or will it flop? Keep your writing as clean and organized as a chef's prep area. And remember, a screenshot or a video is worth a thousand words—or in this case, a thousand lines of code.

Emotional Baggage: Keep It Checked

It's natural to get steamed up when you hit a bug, but remember, a bug report is not a place to vent. Keep the tone as cool as a cucumber raita. Stick to the facts, and leave the spicy outbursts for your biryani.

Feature Requests in Disguise

A feature request masquerading as a bug is like mistaking cardamom for cumin—they're both spices, but they belong in different dishes. Keep your feature requests and bug reports in separate containers to avoid flavor confusion in the development kitchen.

The Ripple Effect of Poor Reporting

A vague or incomplete bug report can send developers on a wild goose chase, much like sending someone to the market with a shopping list that just says "stuff." Be as specific as a meticulous grocery list, and you'll save everyone a lot of thyme (pun intended).

Conclusion: Serving Up Bug Reports with a Side of Precision

Imagine if writing bug reports were like hosting a cooking show. You'd want your audience (the developers) to follow each step with ease, leading to a perfectly 'baked' solution. While our kitchen (the development environment) might not appreciate literal sprinkles of humor in the 'dough' (the bug reports), our blog can certainly enjoy a light-hearted garnish.

So, as we wrap up our culinary journey through the world of bug reporting, remember: the essence of a great dish lies in its recipe. By avoiding the common pitfalls of vagueness, missing steps, and emotional overtones, your bug reports can be as clear and effective as a chef's prized recipe. Your goal is to present the problem with such precision that developers are guided to a solution as smoothly as a knife through soft butter.

With meticulous attention to detail—and perhaps a cheeky smile as you write—you'll help ensure a smooth and efficient path to a high-quality software product. After all, a well-crafted bug report, much like a well-executed dish, is a thing of beauty that brings satisfaction to all involved. Here's to making the development process not just productive, but also a tad more delightful.

The Essentials of Lean Testing: Streamlining Software Quality and Efficiency

noreply@blogger.com (Unknown) — Wed, 08 Sep 2021 05:36:00 +0000

In the dynamic realm of software development, the importance of efficiency and quality cannot be overstated. This is where Lean Testing comes into play, a methodology that enhances the testing process by applying Lean manufacturing principles to software testing and verification. It aims to streamline testing by eliminating unnecessary steps, reducing waste, and focusing on value-adding activities. The core idea is to make the testing process more efficient and effective by only doing what is necessary to ensure the product meets customer needs and expectations.

The Origin of Lean Testing

Lean Testing draws inspiration from Lean manufacturing principles, which were first developed in the Toyota Production System. These principles aimed to optimize production by minimizing waste and maximizing productivity. Over time, the concept of Lean was adapted to software development, giving rise to methodologies like Agile, and eventually extending to the testing process itself. The transition to Lean Testing was driven by the desire to apply the same efficiency-focused mindset to the testing of software products.

Principles of Lean Testing

The principles of Lean Testing are derived from the broader Lean philosophy and include:

Eliminate Waste: The first principle of Lean Testing is to eliminate waste, which refers to any activities that do not add value to the customer or the product. In software testing, waste could be unnecessary or redundant tests, or bureaucratic processes that slow down the testing process. Lean Testing uses the concept of "feedback" rather than "testing" and "improvement" instead of "correction" to enhance the product continuously.

Amplify Learning: The second principle encourages continuous learning and knowledge sharing within the team. For instance, when one software tester gains new insights, these should be shared with the entire team. Pair testing, where two testers work together on the same module, exemplifies this principle by facilitating early error detection and knowledge sharing.

Decide as Late as Possible: This principle advocates for keeping options open as long as feasible to make more informed decisions.

Deliver as Fast as Possible: Lean Testing streamlines processes to reduce the time from development to delivery.

Empower the Team: Team members are given the autonomy and tools they need to take ownership of the testing process.

Build Quality In: Quality assurance is integrated into every step of the development process, rather than being treated as a separate phase.

See the Whole: This principle focuses on the entire development process and how testing fits into the larger picture, rather than just individual components.

Benefits of Lean Testing

Lean Testing offers numerous benefits, including:

Efficiency: By eliminating unnecessary steps and focusing on value-adding activities, Lean Testing streamlines the testing process, leading to faster delivery times and lower costs

Quality Improvement: Lean Testing ensures high-quality software products by building quality from the start. Techniques such as pair programming, test-driven development, and pair testing are used to integrate quality into the process.

Continuous Improvement: A culture of continuous learning and improvement is fostered, allowing teams to enhance their processes and the quality of their products consistently.

Collaboration: Lean principles of learning and respect encourage collaboration and knowledge sharing. Teams are empowered to make decisions and work together in the decision-making process.

Customer Value: Lean Testing focuses on delivering value to the customer by eliminating waste and improving quality, ensuring that products meet customer needs and expectations.

Remember, The goal of Lean Testing is not just to test faster or cheaper but to make the testing process more effective and valuable. By adhering to these principles, teams can deliver high-quality software products that satisfy customer needs and expectations.

Cons of Lean Testing

While Lean Testing has many advantages, there are also potential drawbacks to consider:

Over-Reliance on Team Expertise: Lean Testing can be heavily dependent on the skills and expertise of the team, which can be a risk if the team lacks experience or knowledge in certain areas.

Resistance to Change: Organizations with established testing processes may face resistance when trying to implement Lean Testing principles.

Potential for Over-Flexibility: Too much flexibility can sometimes lead to a loss of focus or direction, making it difficult to maintain a clear vision for the product.

Challenges in Scaling: While Lean Testing can be highly effective for small teams, scaling the approach to larger organizations with complex structures can be challenging.

In Laura Vanderkam's book, "Juliet's School of Possibilities," we follow the story of Riley, a young professional struggling to balance her work and personal life. The book imparts valuable lessons about the power of priorities and effective time management. Here are some key takeaways from this insightful book, along with examples from everyday life:

The Importance of Priorities: The book emphasizes the significance of setting clear priorities. For example, by recognizing that spending quality time with family is a top priority, individuals can allocate their time and energy accordingly, leading to a more fulfilling and balanced life.
The Power of Saying No: Riley learns that saying no to certain tasks or requests can be empowering. For instance, by declining opportunities that don't align with her career goals, she frees up time for the things that truly matter, such as working on meaningful projects or spending time with loved ones.
The Myth of Multitasking: The book debunks the myth that multitasking is an effective way to manage time. Instead, Riley discovers that focusing on one task at a time, such as completing a work project without distractions, is a more efficient use of her time and energy.
The Value of Self-Reflection: Throughout the story, Riley engages in self-reflection, which helps her identify her priorities and make better decisions. For example, by reflecting on her career and personal goals, she gains clarity and perspective, allowing her to make choices that align with her values.
The Art of Delegation: Riley learns that she doesn't have to do everything herself. By delegating tasks to others, she frees up time to focus on her most important priorities, such as leading a team or working on high-impact projects.
The Importance of Boundaries: Riley discovers that setting boundaries is crucial for maintaining a healthy work-life balance. For instance, by establishing clear boundaries around work hours and personal time, she is able to protect her energy for the things that matter most.
The Power of Small Changes: The book demonstrates that small changes can have a big impact on our lives. For example, by making small adjustments to her daily routine, such as incorporating short breaks to recharge during the workday, Riley is able to create more time for her priorities.
The Value of Self-Care: The book highlights the importance of self-care, reminding us that taking care of ourselves is necessary for maintaining our well-being and productivity. For instance, by prioritizing activities that promote physical and mental health, individuals can perform better in all areas of their lives.

In conclusion, "Juliet's School of Possibilities" offers valuable lessons about the power of priorities and time management. By applying these lessons to our own lives, we can create more time and energy for the things that truly matter, leading to a more fulfilling and balanced existence.

This book is a thought-provoking and engaging read that can help readers rethink their approach to time, priorities, and possibilities

My Journey as a Test Lead: Navigating the Exciting World of Team Management

noreply@blogger.com (Unknown) — Fri, 17 Jul 2020 21:57:00 +0000

Hey there, fellow testers and aspiring leaders! 👋 I'm excited to share my personal experience as a Test Lead, guiding teams of various sizes through the thrilling world of software testing. Let's dive into my journey, including the mistakes I've made and the lessons I've learned along the way.

When I first stepped into the role of a Test Lead, I was both excited and nervous. I knew that leading a team of testers meant more than just managing tasks and schedules. It was about fostering a collaborative environment, nurturing talent, and driving the team towards success. As I began my journey, I quickly realized that communication was the key to everything. However, I made a mistake by not being as communicative as I should have been. I learned that regular one-on-one meetings with each team member were crucial to understanding their strengths, weaknesses, and aspirations. This not only helped me assign tasks more effectively but also built trust and rapport within the team.

One of the most challenging aspects of being a Test Lead was balancing the needs of the team with the demands of the project. I made a mistake by being too bossy and not delegating tasks effectively. I learned to prioritize tasks and delegate responsibilities based on the team's skill sets and workload. This not only helped us meet our deadlines but also ensured that each team member felt valued and engaged.

Another lesson I learned was the importance of continuous learning. I encouraged my team to attend workshops, conferences, and training sessions to stay updated with the latest trends and technologies. However, I made a mistake by not recognizing their achievements enough. I learned to celebrate their accomplishments and provide them with opportunities to showcase their talents.

As a Test Lead, I also had to learn to be adaptable and flexible. I quickly realized that no two projects were the same, and I had to be prepared to adjust my leadership style accordingly. I made a mistake by not being open to feedback and not learning from my own failures. I learned to listen to my team's feedback and adapt my approach to better suit their needs.

One of the most rewarding aspects of being a Test Lead was witnessing the growth and success of my team members. I took pride in seeing them take on new challenges, develop new skills, and achieve their goals. I made a mistake by not recognizing their hard work and dedication enough. I learned to acknowledge their efforts and reward them with awards and recognition.

In conclusion, leading a team of testers has been an exciting and fulfilling journey. I've learned the importance of communication, prioritization, continuous learning, adaptability, and fostering a culture of growth and innovation. I've also learned that being a Test Lead is not just about managing tasks and schedules, but about nurturing talent, building trust, and driving the team towards success. I've made my fair share of mistakes, but I've learned from them and grown as a leader. I hope my personal experience as a Test Lead has provided you with some insights and inspiration. Remember, leading a team is a journey, and every step along the way is an opportunity to learn, grow, and make a difference. Happy testing, and keep striving for excellence!

Navigating Remote Pair Testing: A Professional Account of My Experience

noreply@blogger.com (Unknown) — Wed, 15 May 2019 10:52:00 +0000

In my recent role as a software tester, I was tasked with the implementation of a lockbox banking feature into our customer invoice system. This project was unique, as it required a collaborative approach known as remote pair testing, where I worked in tandem with a developer over the phone. This blog post is a reflection on my journey, offering a clear and professional perspective on the process and its effectiveness.

Understanding Lockbox Banking

Lockbox banking is a service designed to streamline the payment process for businesses. It operates by having customers send their payments to a specific post office box managed by the bank. The bank then processes these payments, opening the mail, scanning the payment documents, and updating the company's accounts receivable. This service is particularly beneficial for businesses handling a high volume of mail payments, offering an efficient and secure method of processing these transactions.

The Rationale for Pair Testing

During the initial stages of our project, we encountered a significant number of bugs. This situation raised concerns about the quality and progress of our work. To address this, we decided to adopt pair testing. This collaborative approach allowed us to leverage our individual strengths and perspectives, leading to a more comprehensive examination of the software and a substantial reduction in bug counts. This strategic decision not only improved the quality of our product but also fostered a collaborative environment that aligned with the central principles of Agile development.

My Journey with Remote Pair Testing

Rapid Bug Identification and Resolution: One of the most significant advantages of working with a developer over the phone was the speed at which we could identify and resolve issues. My focus on potential user experience issues, combined with the developer's technical expertise, allowed for efficient problem-solving, accelerating the development process.
Reduction in Bug Count: By examining the software together in real time, we were able to identify and address many potential issues early in the development process. This proactive approach resulted in fewer bugs reaching the final stages of development, culminating in a more robust and dependable feature.
Delivery of a High-Quality Product: Our collaborative efforts during pair testing ensured that the lockbox banking feature underwent a rigorous evaluation process, satisfying both the technical requirements and the user experience criteria. The immediate feedback loop and the ability to make on-the-fly adjustments meant that the end product was not only operational but also refined and user-centric.
Enhanced Team Dynamics: An unforeseen yet valuable outcome of pair testing was the positive impact it had on our team dynamics. This method of working dismantled the traditional barriers between the development and testing teams, fostering an environment of open dialogue and mutual respect. The result was a more unified and efficient team, better equipped to face the challenges of the project.

The Realities of Remote Collaboration

Remote pair testing presented its own set of challenges. It demanded full engagement from both parties, often requiring us to synchronize our schedules to ensure effective collaboration. The need for rapid adaptation during the testing process also introduced a level of mental agility that could be demanding at times.

However, the advantages of this approach were significant. Pair testing facilitated a dynamic exchange of knowledge and skills. As the tester, I was able to share my insights into the user's perspective, while the developer provided a deeper dive into the technical aspects of the software. This reciprocal learning experience contributed to our professional development and deepened our collective understanding of the project.

Conclusion

The process of implementing the lockbox banking feature through remote pair testing was a journey filled with both challenges and triumphs. It highlighted the importance of collaboration and adaptability in achieving project goals. As we continue to navigate the world of software development, this experience serves as a reminder that with the right approach, collaboration can overcome the challenges of distance, leading to successful projects and stronger teams.

Illuminating the Tester's Path: Lessons from 'Are Your Lights On?'

noreply@blogger.com (Unknown) — Wed, 20 Jun 2018 12:13:00 +0000

As a software tester, diving into the pages of "Are Your Lights On?" by Donald C. Gause and Gerald M. Weinberg was akin to embarking on a journey of enlightenment. This book, while not specifically about software testing, has profoundly reshaped my approach to problem-solving in the testing arena. Here, I share with you ten transformative lessons that have not only illuminated my path but could also brighten yours.

1. Starting with the 'What'

Before you leap into action, pause and ask yourself, "What exactly is the problem here?" This initial step of clearly defining the problem is often overlooked, yet it's the cornerstone of effective software testing. It's a reminder that understanding the problem is half the battle won.

2. Seeing Through the Stakeholder's Eyes

Every problem has an owner, and recognizing their perspective is crucial. This insight has taught me to prioritize and address issues more effectively, ensuring that my testing efforts align with the stakeholders' needs and concerns.

3. Unleashing Creativity in Problem-Solving

The book paints problem-solving as an art form, encouraging creative thinking. This perspective has inspired me to explore unconventional approaches in testing, leading to more innovative and effective solutions.

4. The Art of Asking Questions

Asking the right questions is a powerful tool in the tester's arsenal. This strategy has been invaluable in uncovering the root causes of bugs and issues, allowing for more targeted and efficient testing efforts.

5. Peeling Back the Layers

Solutions often masquerade as problems. I've learned to peel back the layers to identify the true issues at hand, sharpening my ability to discern and tackle the real challenges in software testing.

6. Reframing the Problem

The advice to restate the problem has opened up new avenues of thought for me. By reformulating the problem statement, I've discovered alternative approaches and solutions that were not immediately apparent.

7. Connecting the Dots

Understanding that problems can be interconnected has been a game-changer. This realization has helped me trace issues to their source more effectively, leading to more comprehensive testing strategies.

8. Weighing the Consequences

The book cautions that solving one problem may inadvertently create others. This lesson has made me more mindful of the potential impacts of fixes, ensuring that my solutions don't lead to further issues down the line.

9. Choosing Your Battles

Not all problems are worth solving, at least not immediately. This wisdom has helped me prioritize testing issues, focusing my efforts on those that have the most significant impact.

10. Finding Joy in the Journey

Lastly, the engaging tone of the book has reminded me to find joy in the problem-solving process. This mindset has transformed my role as a tester into a fulfilling pursuit, filled with curiosity and discovery.

In conclusion, "Are Your Lights On?" has been a beacon, guiding me through the complexities of software testing. The lessons I've gleaned from its pages have not only enhanced my problem-solving skills but also enriched my professional journey. Whether you're a seasoned tester or just starting out, I believe these insights can illuminate your path too, turning challenges into opportunities for growth and innovation.

Class & Instances

noreply@blogger.com (Unknown) — Thu, 26 Feb 2015 01:40:00 +0000

In Object Oriented world a class is a blueprint for the objects we want to create in code.

For example, let's say we wanted to represent a car in code. We can define a car using a C# class through attributes and behaviors. Some of the different attributes that make a car unique are its model, make, and color. For the car's behaviors, something a car does is start, so we can define this behavior.

Putting this into code, we would have a car class with string attributes called model, make and color. We can also refer to these attributes as fields. This class would also have methods called start and stop because a car starts and stops. This is a behavior we want to define for the car.

Car Class

string model;

string make;

string color;

start();

stop();

From the class blueprint, we can create several different types of cars. For example, one car could be a BMW 3 Series and have blue color. Another car might be a Merc Benz Class C and have green color. The way we create these individual cars from our car class blueprint is with the constructor.

Now, both of these cars have a make, model, and color defined by the class blueprint, but the values of these attributes are different, depending on the car. Each of these cars can also start and stop so they would be able to call the start and stop method. This makes the Blue BMW car and the Green Merc car instances of the car class.

These cars were constructed from the car class using a constructor, making them instances of the car class.

Speak Your Users’ Minds

noreply@blogger.com (Unknown) — Sat, 17 Jan 2015 10:53:00 +0000

The user based testing always fascinates me as the product is analyzed from the perspective of living person rather than dead code or design. A user is one who uses the “Product” or “Services”, the one who makes a product HIT or FLOP.

In last few years, I have observed that businesses are seriously considering the products from user’s point of view. Did you also update the test cases for the last product you tested? Does your test plan include scenarios for user based testing? Do you think about “User Experience” while testing the product?

The User Experience Testing or UX Testing, as most of the time we call it, is conducted to find out how user feels after using the product. Does user feel great about the product and come back for it or was it last time s/he used this product? Here, the product is tested against the emotions of the user and that is what makes it most difficult kind of testing.

When I think of Happy User Experience, the first example which comes in my mind is of IPhone. There are multiple brands with hundreds of smart phones running on different platform but still a large chunk of young population want to buy IPhone; even after the higher cost. Good user experience guarantees the Quality and people are ready to pay higher if product makes them happy.

How do you feel about IRCTC website?

Are you eager to try alternative of IRCTC, if available? If answer is “Yes”, I guess I made my point.

There are five factors I realized during testing which directly affect the user experience.

Contextual: The product should be in context with the user requirement. If not, forget user will ever use the application.

Desirable: The need is over once product is contextual. Give user what he was wishing in the product. Little more than what was needed.

Usable: The product should be easy to use. Don’t make user to go and check for the manuals.

Accessible: The product is accessible to all users – abled and disabled.

Trustable: The user should have trust on what product does and what it conveys. Branding plays an important role in building the trust. Remember ‘I’ of HICUPPSF by Michael Bolton.

Customer is the King and King has broad spectrum of options. Now, it’s just not eBay only, there are Flipkart, Amazon, Tesco, SnapDeal and 50 other online retail and market places. Everybody is selling the same product then how one can differentiate itself from the herd. This is high time to include the user based testing in your test plan. You want to guarantee success of your product – Speak your users’ minds. Remember, the $300 million button.

How about using a Spell Checker?

Using a spell checker is a good habit. Use it occasionally :)

Secured Payee Account Number, Really?

noreply@blogger.com (Unknown) — Thu, 25 Dec 2014 18:30:00 +0000

This one was found in ICICI bank website while adding the new Payee. The Payee Account Number is masked for the first time but displayed in confirmation field.

The Orphan Error Message

noreply@blogger.com (Unknown) — Tue, 23 Dec 2014 18:30:00 +0000

This error message I used to see every time I started my system.

It took me a while to find out that this error message belongs to iMindMap application which I removed from my system. Don't you think they shall display the application name while displaying such errors?

PSR - The tool to write Effective Bug Report

noreply@blogger.com (Unknown) — Mon, 22 Dec 2014 12:19:00 +0000

How often as a tester do you think that you spend a big chunk of your testing time in reporting the defects rather than testing actually? There could be multiple reasons of this:

The defect template could be complex
You might be slow in typing
You might not be so good in vocabulary

How many times did it happen that you logged a defect and developer rejected because the steps were not detailed enough to replicate the issue.

A good bug report is responsibility of the tester and each stakeholders expect the same. I noticed the same issue within my project; Team spend too much time on writing effective bug reports. On average it takes 30 minutes to log a defect. That is a big time. If one found 6 defects that means the person had spent around 3 hours to report those defect. That was something pinning me for last few months and I was eagerly looking for a solution to get over this problem.

Recently, I came to know about “Problem Steps Recorder” which caught my attention. Microsoft has provided this utility in Windows 7 to record the problem steps in Microsoft Window. PSR captures the events happening on the screen and create a low size zip file with all steps and screenshots happening at the desktop.

PSR also provides the facility to annotate the screenshot during the runtime. Just select the screen area and enter your comment. The same will be added in the Report. Isn’t it awesome?

You can even disable the screen capture as per your need.

This is kind of what I was exactly looking for. The next step was to know how team feels about it.

On a good day, I called my team for training and demonstrated this tool. They all were quite excited and wanted to use it immediately and there was no reason to stop them. So, I asked them to use the tool and let me know their opinion. Till now, I got very positive feedback about the tool so I am thinking to take it to next level; to get it approved from important stakeholders, mainly Project Manager and Customer. No matter how others’ take this, it has already become a mandatory part of my Test Armory.

If you practice testing, How about using it in your practice sessions? Please share your opinion in this thread.

Website Accessibility Evaluation Methodology

noreply@blogger.com (Unknown) — Fri, 03 Oct 2014 21:35:00 +0000

Being an Accessibility Enthusiast, I generally get a question – How to evaluate accessibility of a website? Is there any approach or methodology which guarantees the accessible website? Well, I don’t think any methodology would guarantee a 100% accessible website until you get the website tested from real users – the users who face the pain of inaccessible websites.

Anyway, when the question became too common – I thought it's time to work on this and here I am presenting a methodology to evaluate accessible website. This methodology is evolved from fine tuning of industry’s best practices and Website Accessibility Conformance Evaluation Methodology by W3C.

This methodology includes the different phases of accessibility evaluation starting from collecting the baseline information to the last phase of retesting the fixed issues. This methodology can be used for existing websites and during earlier development stages of the website. This methodology can be used for evaluating static, dynamic, mobile and other types of websites.

Draw a Line
The objective of this phase is to collect the information and understand the accessibility requirement of the customer. This is accessibility evaluation preparation phase wherein tester collects prerequisite information such as target website, business nature, current accessibility status, identification of Assistive Technology and conformance standards to be implemented.

Let’s Explore
The tester explores the target website to get thorough understanding of website functionality, use and purpose. The exploration carried out in this phase helps in later stages when evaluation of target website takes place. The objective of this phase is to identify:
• Critical web pages of the website – The website is explored to identify mandatory functionality and critical web pages which are core of the website and might directly impact the business. The outcome of this step is the list of all critical web pages and mandatory functionality that user performs on the website.
• Common web pages of the website – The website is explored to identify the common web pages of the website. These web pages are generally directly linked to home page and main navigation of website and sometimes represent the different states of website. The outcome of this step is the list of all common web pages on the website.
• Dynamically generated web pages – The website might have web pages which are generated dynamically based on user input and important for the website. For example, product listing page on a website. The website is explored to identify such web pages on the website.
• Other relevant web pages – Here, the website is explored to identify the web pages that are more relevant to users with disabilities and accessibility of website such as web page informing about the website accessibility features, settings, shortcuts etc. The outcome of this step is list of such web pages.
• Variety of web page types – The target website may have web pages of variety of styles, templates, layout and structure, navigation and visual design etc. In this step, the website is explored to identify such web pages on the website. The outcome of this step is the list of all such web pages differentiated by varieties.

Collect the Samples
The objective of this step is to pick up the sample of all type of web pages which represent the target website. The purpose of this sampling procedure is to ensure the good enough accessibility evaluation of website with reasonable confidence. The sample set should include:
• Sample set of all critical web pages of the target website
• Sample set of Common web pages of the website
• Sample set of each dynamically generated web pages
• Sample set of Other Relevant web pages
• Sample set of each web page type
• Sample set representing the complete process
The sampling procedure could be skipped where it is feasible to evaluate all web pages in the target website; all the web pages are considered for accessibility procedure in such situation.
The selected sample sets are further evaluated to identify the common components such as navigation menu bars, headers and footers, search form etc. which do not require the re-evaluation on each occurrence.

Use Automation Tools
During this step, the selected sample set of web pages are evaluated by multiple automation tools as per the conformance standard selected in first step. The objective of automatic testing is to quickly identify the accessibility issues in the selected set of web pages of the website. The outcome of testing in this phase is:
• a list of confirmed accessibility issues which are failed to meet success criterion of selected conformance standard
• a list of potential accessibility risks which require manual intervention before next action
• a list of features which meets with the success criteria of selected conformance standard

Manual Testing with Assistive Technology
The tester further evaluates the selected set of web pages of target website manually to conformance with each success criterion of selected standard. The objective of this step is to identify the issues a disable user might be facing in using the target website. All content of the website is evaluated:
• to find out any occurrence of failure to meet success criteria of selected conformance standard
• to find out any occurrence of failure during the interaction of each web page and web page state along with complete process
• to find out any occurrence of failure in using the website with assistive technologies selected in first step
• to verify the list of potential accessibility risks generated in previous step
• to ensure that all content is supported by accessibility features

Make a Report, Retest
This step focuses on the analysis of reports collected from automated testing and observation made during manual testing process. The purpose is to identify all false positives and false negative before reporting the issues in the bug tracker. A report is produced with analysis outcome and recommendations and suggestions for all stakeholders.

Further, a decision should be made on retesting based on the outcome of the analysis. Retesting would have similar approach of testing - using automation tools followed by manual testing with AT.

Web A11y* Beyond Guidelines

noreply@blogger.com (Unknown) — Thu, 11 Sep 2014 13:39:00 +0000

(A11y* - Accessibility)

Think about accessibility testing of a website - "WCAG" - the first word which comes in mind (Section 508, in some cases), why?

We are so obsessed of following the guidelines. When I second these guidelines are important piece of information, we also need to understand that these guidelines are mere documents for reference, they are not the laws. We shall start thinking of accessibility beyond the guidelines. The presentation is an attempt to point out the issues of blindly following the guidelines and how can we get over such issues.

Questions are welcome :)

Audio Accessibility

noreply@blogger.com (Unknown) — Sat, 09 Nov 2013 22:31:00 +0000

In my last blog post, I discussed about making the accessible videos. This post is dedicated to audio accessibility. The mind map presented below provides an insight on audio accessibility.

For Questions, Suggestions and Feedback; please leave your comment below.

Making Videos Accessible – 7 tips for making videos accessible on the website

noreply@blogger.com (Unknown) — Tue, 26 Mar 2013 17:24:00 +0000

A website has many ways to share the information with their users such as textual content, Pictures, Audios and Videos. As a picture is worth a thousand words, similarly, a video is worth a thousand pictures. Thousands of articles, blog posts and white papers are written and available over internet on how to make images accessible for users with different abilities but there is not much information on how to make videos accessible to the users.

The little information which is available is not much helpful as either it is incomplete or it revolves more around visual and auditory disabilities and does not focus on other kind of disabilities. The possible reason for this could be that the less number of videos are published when compared to the images on any website. But this should not allow web masters to ignore the accessibility around the videos. The purpose of writing this article is to provide a feasible solution for making the videos accessible for all class of users of the websites.

Why Videos should be made accessible?

A video is more informational than any other medium. For example, an image can only show how to use a device but a video can be more informative by mimicking the uses of the device; this makes a video more user friendly for the users. Making videos accessible will help the different classes of users who can’t effectively use the videos for whatever reasons.

How to make videos accessible for the users?

The ideas listed below are outcome of brainstorming I did on the subject and can be used to make the videos accessible for any class of website users.

Remember, these ideas do not help web masters to make accessible videos; they help web masters to make videos accessible for their website users.

1. Provide Captions/ Script Transcriptions along with the videos

The Captions help users with aural disabilities to learn the content of the video. There are two types of captions – Open and Closed. The Open captions are burned-in with the video while Closed Captions are written in separate file which run with video. Personally, I think that Closed Captions should be used with videos because user can control them by switching on/off.

Script Transcriptions are the text content of the video’s provided in separate file. They are similar to Closed Captions file except time stamp is not needed for Transcriptions.

2. Alternative Text for Videos

Does this sound weird to you to provide alternative text for videos as it is supposed to be for images and not for videos?

What is a video? – A collection of moving visual images.

The first guideline to make any website accessible is to provide alternative text for all meaningful images; then why videos are exceptional. It is perhaps because of videos make more sense to user. So, why do we need alternative text for videos?

We need alternative text for those videos which do not make sense to the users. For example, when I watched the movie ‘The Matrix’ for the first time, I liked the action sequences in the movie but the story didn’t make much sense. By the second time, the movie made some more sense to me; but still a few things were unclear. Then, I read the plot of the movie and I got the gist of it. Next time, it was all clear. In fact, reading the plot of the first part of this movie made it easier for me to understand the rest of the sequels.

Decision of providing alternative text with the videos should be context – based. For example, if Caption/Script Transcription is already available and descriptive enough, the alternative text can be ignored. But, a video with no audio should have alternative text to explain the content to users with visual/cognitive disabilities.

3. Accessible Media Player

An accessible media player could help more than anything else to make the video content accessible for the users. For Example,

Having a keyboard accessible media player can help users with visual, aural, mobility or cognitive disabilities.
For low vision/partial blind users, I advise users to use media player with Full Screen and zoom options so that users can set the video to adequate size to view it.
Providing a volume control in the media player can be a good idea for the users who are hard of hearing. They can set the volume to an adequate hearing level.
The web media player being used should also have features such as Play/Pause, Forward/Backward and Captions On/Off buttons. These features might seem common and available in almost every web media player but they do help the website users to a great extent. For example, If a user is hard of hearing, he can go back to hear the missed word or a user with cognitive disability might want to control the video and play according to his comfort.

If your media player has such features, don’t disable them. Let the users use them.

4. Validate Videos with PEAT

An animated segment of a film promoting the 2012 London Olympics was blamed for triggering seizures in people with photosensitive epilepsy. The charity Epilepsy Action received telephone calls from people who had seizures after watching the film on television and online. In response, it was reported that London 2012 Olympic Committee removed the offending segment from its website. (Courtesy: Wikipedia)

If your videos have red flashes, it is advised to use PEAT (Photosensitive Epilepsy Analysis Tool) to validate the videos to identify the seizures risk.

5. High Quality/High Definition Videos

The quality of the videos is reduced when viewed in full screen mode or zoomed-in, making it difficult for user to view the videos; especially users with low vision. To avoid degraded video quality and better viewing, it is advised to provide high quality videos.

6. Explicitly mention if there is ‘No Sound’

Most of users think that Captions/Transcript scripts are not needed for videos with no sound but that is an incorrect perception. Providing Caption or Transcription Script for such videos is also as important as compared to videos with audio. For example, if not informed about ‘No Sound’, a user with aural disabilities might think that supported transcript is not provided and may feel discomfort about it. In such cases, mentioning it explicitly can help user in a great way as he can concentrate totally on the video without having to look elsewhere for the transcript.

7. Keep the Content Simple

Keep the content of the video simple, if possible. Using small sentences/dialogs and simple words can make the content more accessible for users with cognitive disabilities. Provide alternative text for complex or third parties videos where content can’t be controlled as webmaster.

Why Sign Language translation can be avoided?

Although, WCAG 2.0 suggests using Sign Language Translation; I personally feel that using Sign Language Translation is not a mandate and can be avoided for various reasons listed below:

The sign language could differ in different geographical locations
The approach is costlier than any other approach such as providing Transcription Script or Captions.
Limited user base – Sign Language Translation would be useful only for single class of users suffering with aural disabilities.

These ideas are based on my understanding with the subject. Let me know if you think otherwise.

Should you really follow BEST PRACTICES?

noreply@blogger.com (Unknown) — Wed, 13 Mar 2013 20:06:00 +0000

Once upon a time, not long ago, a developer created his own personal website. To keep the unauthorized users away, he added the login page. Being an internet savvy himself, he always knew how hackers plan their attack. So, instead of displaying direct error message for login fields, he showed a common message as “Username/Password is incorrect. Try again”. This was a smart move from him as now hacker couldn’t know which input was wrong. He showed this message to one of his developer friends and he followed the same. Similarly, it became BEST PRACTICE to display the common error message on the Login page.

The only best thing about BEST PRACTICES is that they are best in some contexts and worst thing is that people have tendency to follow the best. In fact, sometimes they are followed by everyone and hence become common. There can’t be hundred best students in class of hundred. Only one could be best in each subject among the hundred; others could be good, very good, average and poor.

The story said above is not a story, it is reality. The idea to change the error message worked for first developer but it didn’t work for his friend. Why? Let’s see.

The unauthorized user entered the invalid username and password, system displays an error message “The email address or password you entered isn’t correct. Please try again”. Quite good. The user doesn’t know which is incorrect – username, password or both. (This is similar to what first developer did and other followed.)

Then user opened “Forgotten your password?” page and entered the same email id. The system displayed the error message that entered email is not registered with website. Boom. The security provided by the previous error message is violated by this message. Now this unauthorized user knows that this is not the correct user name so he can put his energy to find the correct user name. He has got a direction to move. (In our story, first developer didn’t provide the Forgot Password page but others did. So his solution worked for him but not for others.)

The problem is people are so obsessed of following best practices that context is side-lined in most of the cases. See the below example:

Here, if an unauthorized user enters an invalid Email address – system clearly tells him that account doesn’t exist.

In other case, when user enters correct email and incorrect password, system displays “Email/Password combination is wrong” (BEST PRACTICE). From previous message, it is obvious that only password can be wrong in this case but as I already said that people are obsessed of following the BEST PRACTICES that they miss the tweaks.

There are two important learning from above examples:

The BEST PRACTICES are best in their contexts and might not work for you if context differs. Do what work for you and that will be your “BEST PRACTICE”. Moreover, it doesn’t make sense to me that if everyone is following the same then how it can be called as “BEST PRACTICE”. It should be called as “GENERAL PRACTICE”.
Don’t forget to verify linking between error messages in your application. We have seen in above scenarios that one error message is violating the rule of other. (The linking between Error messages might be new to many and should be practiced.)

If I were testing the same Forgot Password page for the website displayed above, I would ask developer to place a message like “An email will be sent shortly to registered email if it’s valid”.

Now, don’t make this as BEST PRACTICE.

Are Text-version websites really needed?

noreply@blogger.com (Unknown) — Mon, 11 Mar 2013 12:56:00 +0000

Today, while browsing through the web, I found a website named Office for Disability Issues. As mentioned on their website, “The Office for Disability Issues (ODI) is part of the Department for Work and Pensions and works closely with the Minister for Disabled People, other government departments, disabled people and a wide range of external groups.”

As expected from description published above, the website is well designed to make accessible to users with different abilities. WAVE could find one and only one accessibility issue in the Home Page. Isn’t it Impressive?

The site provides different accessibility features such as Update Font Size, Change background and foreground colour etc. but the feature which caught my interest was Text version of the website.

Initially, I found the Text version of the site very useful; especially, to users with visual disabilities who use screen reader programs to access the web. Later, I couldn’t think of any other user who prefers a website without images. (Quasi-disabilities such as slow internet connection are not in scope in this context. That can be achieved by disabling the images in browser, if needed.)

A text version website may be useful to visually challenged users; but it will not be friendly to the users who can see. In fact, they might find such websites boring or difficult to use.

There is very old proverb – A picture worth a thousand words. A website having images with correct, sensible and comprehensive alt text will be useful to large group of website visitors including users with cognitive and visual disabilities. A website designed to make accessible to everyone might be a better choice rather than creating separate versions of a site for users with different disabilities.

Think.

Nokia N8: Is it really accessible? Find yourself

noreply@blogger.com (Unknown) — Mon, 25 Feb 2013 10:13:00 +0000

This report might concern to some people same as it initially did to my dear friend and very good tester Santhosh Tuppad -Why am I testing and writing a report for a phone which is ousted from the market? The simple reason is that I currently own only this phone and I don’t have any other option until it stops working or I loose it somewhere or somebody gifts me a latest phone.

I have Nokia N8 with me since last two years but it was first time when I tested it from accessibility point of view - The reason is my current interest in the area of accessibility testing.

Before moving to my report, I would like to share brief history of Nokia N8: (Credits: Wikipedia)

The Nokia N8 is a touchscreen-based smartphone developed by Nokia. The Nokia N8 is the first device to run on the Symbian^3 mobile operating system and Nokia's flagship device of 2010. The N8 became the product with the most customer pre-orders in Nokia's history up to the point of its release and sales in Q4 2010 have been estimated to be almost 4 million. The N8 has a capacitive touchscreen and the first Nokia phone with multi-touch.

Believing the numbers it can be interpreted that it was one of popular phones from Nokia so this report might interest to many mobile testers and phone users.

For ease of understanding, I have divided my reports into three zones: Red, Yellow and Green. Red zone is danger zone which lists the accessibility issues of the phone. Contrary to Red zone, Green zone is the safest zone which lists the accessibility features. Yellow zone is placed somewhere mid of these two.

Red Zone

No Compatibility for Hearing Aid: One of the biggest drawbacks of Nokia N8 from accessibility perspective that it doesn’t not provide compatibility with Hearing aids which could have helped user with Hear loss.

Voice Command: Nokia N8’s Voice Command feature seems most problematic area to me. There is no hard button for Voice Command which makes it difficult to use for visually challenged user. Placing a shortcut can’t be helpful as user can not open Voice Command by giving a voice command. Other drawbacks which I noticed are:

The shortcut buttons are small in size which can make it difficult to use for user with partially eye sight / motor disabilities.
It has limited functionality. You can use it for single word basic commands, don’t expect much from this.
The other most irritating feature is that it auto closes after 5 seconds. User needs to enter commands within 5 seconds otherwise ‘Poof’. For a user who stutters (for example, stuttering which causes involuntary silent pauses or blocks) can be quite difficult to use it.

No Stylus: Nokia N8 is delivered without any stylus. A stylus can be useful for the user’s with motor disabilities and not every stylus can be used with Nokia N8 because of Capacitive Touchscreen which requires an electrical conductor such as Human body to send the signal. Such devices need special capacitive stylus to work upon.

No Screen Magnifier: A screen magnifier is a very good and one of essential tools for users with low vision but Nokia N8 is missing it. Although they have provide Zoomer which have limited functionality and placed in Yellow Zone.

Yellow Zone

Font Formatting: This is an area which could have been made most useful for users with low eyesight but N8 miserably fails here. N8 has feature to change the font size, which ironically, applicable on text messages only. The other text such as application labels remain same.

Also, user can use only one default font style provided in the phone. I couldn’t find any feature which changes the font style used in the phone.

Zoomer: Nokia provides Zoomer to zoom in the pictures and the text content. That’s all. You are unable to see any icon, it’s not their problem. Their is no feature of screen magnification or resizing the icons.

Screen Reader: There is no default screen reader provided in Nokia N8. Users need to install a 3^rd Party tool if they need one. Thankfully, Nokia N8 has a Message Reader which can read inbox messages for user.

Green Zone

The features listed in green zone might be common to any other smart phone but they definitely need a mention here.

Alert: N8 can alert user in many ways according to user’s preference. It has different alert options like Ringing, Vibrating, Flashing which finally adds some plus points to its credits.

Conversation: Messages are displayed in conversation form. It means a user can view complete conversion made with another user quickly without any hassle. This feature can be useful for users with bad or short term memory.

Help: This is the feature which I liked most about N8. It provides relevant help on every single screen. Help is just one tap away from the user.

Shortcut: Although, this feature doesn’t seem anything special for a smart phone but I believe it as one of the important accessible feature. It helps user to open an application quickly and avoids the longer path. Important feature for users with motor disabilities.

Consistency: The phone has consistent functionality on each screen.

Associating Caller’s Image and Tone: User can associate caller’s image and separate tone with the number which could help user to identify caller easily. The feature can be useful for short term memory and visually challenged users.

Compatible with Text Phones: N8 is compatible with the Text Phones. A text phone can help user to type and read conversation during a call, rather than using speech and hearing communication.

***************************************************************************************

Conclusion: Nokia has provided some basic accessible features in N8 which every other phone in market have. They should give more importance to accessibility and usability in their new upcoming phones if they really want to have an edge over other mobile giants such as Apple or Samsung.
