Rethinking Our Job as Software Testers: We Should Try to Test as Little as Possible

jmcallister@sqe.com (Software Quality Engineering) — Wed, 12 Jun 2024 18:05:27 +0000

DevOps transforms testing from finding all bugs to prioritizing critical ones. Risk assessment helps testers focus on high-impact areas. Testing can be pre-release (critical issues), post-release (resolvable issues), or out-of-scope (low-impact). Testing should align with business goals and user stories. Data science helps measure and improve software quality.

Code with Care: Security Testing in Confidentiality-Driven Industries

Deep learning, particularly Convolutional Neural Networks (CNNs), has transformed object detection in computer vision. These AI models excel at identifying and pinpointing objects in images and videos with high accuracy. However, integrating metadata like object class, location, and time with AI object detection unlocks even greater potential. This enriched data provides valuable insights for applications in autonomous vehicles, healthcare, retail, and manufacturing.

A Comprehensive Guide to Responsive Testing

Responsive testing ensures websites look and function well across devices by testing layout, functionality, and performance on various screen sizes and browsers. It's crucial for consistent user experience, navigation, image display, and website robustness. Testing methods include browser developer tools, real devices, usability testing, and performance testing. Common challenges include outdated browsers, device-specific behaviors, and network speeds. AI, Machine Learning, and Real User Monitoring are emerging trends in responsive testing.

Don’t Let Load Testing Lead You Astray

While traditional, "closed system" models might seem familiar, they miss the unpredictable nature of real user arrivals. This article highlights how open system models, which mimic real-world user behavior, expose performance bottlenecks at high load that closed models can't catch. Remember, arrival rates, not virtual user counts, are the key to unlocking accurate load testing results.

Testing Kubernetes Clusters: A Practical Guide

jmcallister@sqe.com (Software Quality Engineering) — Fri, 05 Jan 2024 21:18:56 +0000

Thorough testing of Kubernetes clusters is critical for any organization that values high-quality application delivery, resilience, and security. An untested Kubernetes cluster represents major risks for your organization. Therefore, a comprehensive Kubernetes testing strategy is not just good practice—it's essential for the success of your IT and development projects.
