My latest game!

2011-04-29T00:03:00.000-07:00

It has been nearly a decade and a half since I last developed a game and I am glad that it may turn out to be really good. In HTML5 and Javascript, it is meant for both web and mobile platforms that have browsers that support HTML5. Here is the link - http://sites.google.com/site/jvravichandran/html-game Below is the screenshot. Of course there have been some modifications...:) Enjoy playing the

A simple wrapper for C++ class

2011-01-26T03:53:00.000-08:00

Interoperability between a C++ class and a C# object is a huge issue as is obvious by the fact that C++ has a static object structure and C# has a dynamic object structure. So, lots of interoperable wrapper classes and interfaces have to be used to create communication channels for the two different runtimes. Not so anymore with the introduction of the new DLR (Dynamic Language Runtime). The DLR

Making NUnit 2.5.5+ work with .Net 4.0

2010-06-08T01:26:00.000-07:00

It seems that many have found NUnit 2.5.5 not working with DLLs compiled with .net 4.0. NUnit 3.x has been designated to work with .net 4.0; till that time make a modification to the NUnit config file and add this startup element under the main configuration element : <startup> <requiredRuntime="v4.0.30319"/> </startup>

BDD + UADD

2010-05-31T23:57:00.000-07:00

This is a cool way of satisfying most of the stakeholders in the development process as well as automating, to a large extent, the scenarios and the acceptance criteria of the tester, without burdening the software development process with too many artifacts or overheads. In fact, you can accomplish both BDD (Business ("B" for Business or Behavior? I will be exploring this in the upcoming Agile

Decision & Scenario Tables in Slim

2010-05-06T04:14:00.000-07:00

There are two exciting features in Slim - the Decision Table and the Scenario Table. Below are the screen shots of both: A Scenario table, as in the above image, does not by itself do anything and that is why the Scenario does not show green but, when combined with the Decision table, you get the desired test behavior as in the below image. Every scenario described in the scenario table gets

The Slim Framework

2010-04-30T04:42:00.000-07:00

Agile is getting leaner and leaner or so the efforts around the world indicate! And keeping in tune, tools like Slim for .net attempt to reduce complexity in lifecyle activities thereby infusing more agility into the development process. Slim is the all new Fitnesse-based Test System that has distinct advantages over its pre-decessor - Fitnesse. Fit is, even now, the default test runner in

Unit & Mock Testing "New" and "Override" implementations

2010-04-30T02:56:00.000-07:00

It has been quite a while since I posted to my blog because I didn't have anything interesting to publish. But now, here is an interesting challenge. Unit testing the "new" and "override" keyword implementation. Since, the "new" keyword was introduced to hide a base class implementation there has been a lot of arguments on how to actually show the execution of these methods in a polymorphic

Mobile tweeting is the only resolution I have made for the new year 2010!

NUnit support for .Net 4.0

2009-11-09T02:33:00.000-08:00

The fix has been committed and NUnit will support .Net 4.0 framework from ver. 2.5.3 or the future versions. And I am glad I contributed to the fix.

Unit Testing .Net 4.0 with TDD.Net

2009-08-28T07:15:00.000-07:00

Hey, Even if NUnit in its current form does not support .Net 4.0, there is a workaround with Test Driven.Net. Download, install and VS 2010 acknowledges Test Driven.Net and you can run your unit tests right inside VS 2010. It is as cool as NUnit. Here is the code to test the RandomGenerator class:using System;using NUnit.Framework;using RandomCalculator;namespace ClassLibrary1{ [TestFixture]

NUnit for .Net 4.0

2009-08-28T03:59:00.000-07:00

Shucks! NUnit currently does not support .Net 4.0 assemblies or may be expectations are ahead !

Parallel.For XML Parsing

2009-08-27T01:34:00.001-07:00

Another example using Parallel.For. Depending upon the cores in your machine, you will find the code returning different results. MaxDegreeOfParallelism sets the max number of cores to be used for running the parallel forloop. class Program { static void Main(string[] args) { XmlDocument xDoc = new XmlDocument(); xDoc.Load("e:\\JKTAgileAcademy_August2009\

Parallel Computing - .Net 4.0

2009-08-27T01:11:00.000-07:00

Ah. I said, when i watched the TechEd cast in MSDN Tv, i can understand the difference between multi-threading and parallel computing correctly and the importance of cores in a CPU. But that is the only joy that you get from .Net 4.0! I took the plunge, downloaded VS 2010 and wham !, the product literally explodes in your fingers (with a 2 GB dual core laptop)!! Context menus, intellisense menus

Parallel Unit Testing with PNUnit

2009-07-28T04:30:00.000-07:00

One of the great things about the coming version of NUnit is the integration of PNUnit - the parallel Unit Testing tool developed by codice.com.With PNunit, you can distribute your tests across machines and test it for different load and stress scenarios. This distributed testing mechanism also helps in performing "smoke tests". The other advantages, to keep it brief, is that the team that uses

ExpectedException - NotImplementedException

2009-07-23T01:26:00.000-07:00

Recently, i got to thinking about how well suited the NotImplementedException is for Test-First approach of software development.In Test-First or Test-Driven approach, you are required to write your tests first before writing any line of code. For example, if you were to provide for a Calculator class, it is required that you write tests for the class first. But then, how do you write tests for a

Agile NCR Conference 2009

2009-07-18T03:31:00.000-07:00

I presented on "ROI with Agile" and the session went much better than I had anticipated. The conference, itself, was organized as well as last year and soon, we should probably see the NCR conference going international. Its popularity and enthusiasm generated by this conference is engaging and infectious.My colleague, a first time attendee to the conference, was eager to check the budget of such

Generating test cases from an external class

2009-07-02T04:02:00.000-07:00

The TestCaseSource attribute allows you to specify a method or a property, which could act as the source for your test cases. Simple and effective as TestCase attribute is TestCaseSource attribute is better.A simpe rule that you must remember is that the class that contains a source method for the testCaseSource attribute must have a default constructor defined for it unlike the TestCase

Type Inference - NUnit 2.5

2009-06-29T05:55:00.000-07:00

//[TestFixture(12.0,42,TypeArgs=new Type[] {typeof(double),typeof(int)})][TestFixture("Hello", " World!",TypeArgs=new Type[] {typeof(string),typeof(string)})]public class TestClass<targ,targ1> {private TArg val;private TArg1 val1;public TestClass(TArg val, TArg1 val1){this.val = val;this.val1 = val1;}//[TestCase(5.0, 7)][TestCase("Hello", " World!")]public void TestTypesOfArgument(TArg t1, TArg1

Product Development and Agile

2009-06-19T04:50:00.000-07:00

Let us consider a product that has been released in the market and has won accolades for its UI. The next version, minor or major, of the product would obviously benefit from the appreciation but what if the product owners decide to tweak the UI more and settle for the menu’s look, feel and location.Let us say that the below image represents the current menu look – the traditional drop-down menu.

"Flaccid" Scrum ?!

2009-06-17T00:41:00.000-07:00

I read this document of Ken Shwaber www.scrumalliance.org/resource_download/745, in response to a post on Martin Fowler's blog - http://martinfowler.com/bliki/FlaccidScrum.html.Ken Shwaber says, "Scrum is ...it does not prescribe any of the common engineering, risk or people management practices..." and "An intelligent person would change (continuous process improvement)"! and "An intelligent

The Agile "dryndrome"

2009-06-08T01:18:00.000-07:00

When I used Procomm to develop (!) my first software in 1989 for Deccan Herald, a newspaper company based in Bangalore, it didn't seem to be a great activity. Of course, family members went ga-ga over my newly acquired skills and the amount of money that the effort brought in! In fact, I remember my father was almost glad that he had got back more than half the money he had spent in educating me

Wait Cursor for console

2009-05-25T05:28:00.000-07:00

Creating your own cursor for a processing job is always interesting - no matter what the environment is. Below is the code for creating one for console on windows:using System;using System.Threading;public class WaitCursor{public static void DrawCursor(){int y=0;Console.SetCursorPosition(Console.CursorLeft+15,Console.CursorTop+15);for (int i=0;i<10000;i++){>0)y=Console.CursorLeft-1;

Returning a "var" type from a method

2009-04-22T03:05:00.000-07:00

The "var" type is a new introduction in .Net 3.x and it is also well known as an implicitly typed variable. The syntactical constraints are that they can be declared1. Only inside a method.2. only in a local scope.3. only inside the scope of a method call.4. only in an initialized state before being used.So, if you require a "var" type returned from a method, you can do as below:public class

Anonymous Types

2009-04-22T02:51:00.000-07:00

Anonymous types are the most convenient way of working with those types, which do not need extensive usage or heavyweight creational structures.The below code assigns a "var" type with a new instance whose type is/are the value(s) and their corresponding identifiers. var implicitVar = new { Name = "A", Price = 3 };So, if you do a Console.WriteLine(implicitVar.ToString());the output will be:{Name=
