Extreme Programming Adventure

Extreme Programming and Unit Testing in particular is exciting because the Unit Testing
itself serves as Design & accomodates change without great effort, reducing Post production
Testing and Support time and Expense..... Amazing

I took OOAD course offered by Dr. Venkat last Semester, we were introduced to the concepts
of OOAD, Unit Testin, Design Patterns and a lot more.... Programming the professional way
The transition from Object Oriented Programming to Test Driven Development is not easy as
the humans have the tendency to resist change.... I still remember grabbing OO concepts with
my Procedural Programming Biased mind.........

So what is the approach.........
1) Write the Test first before even you write a single line of code, The Test shoild fail in
the absence of your "useful" code... sounds extreme
2) Write the minimum amount of code to make the Test Pass....
3) Write useful code and Refactor..... Simple

RED, GREEN, REFACTOR is the key to Unit Testing, Red for failing the Test, Green for writing
code to make the Test Pass and Refactor to achieve Cohesiveness

Tools:
Though you can also write your simple Unit Testing FrameWork, its not really the best thing
to do, lots of Unit Testing tools like NUnit for C# and JUnit for Java is available. Please
check out http://www.nunit.org/
http://www.junit.org

WPF How to Dispose ViewModel when the associated UserControl (Not Window) closes?

Note: If your WPF UserControl is hosted in MFC Window, you may want to clean-up the ViewModel that is DataContext of your UserControl. Since Unloaded event is not called reliably for the UserControl when the hosting MFC Window closes, there is a need for another solution. XAML: < UserControl  x : Class = "Views.MyUserControl"               xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation"               xmlns : x = "http://schemas.microsoft.com/winfx/2006/xaml"               xmlns : mc = "http://schemas.openxmlformats.org/markup-compatibility/2006"                 xmlns : d = "http://schemas.microsoft.com/expression/blend/2008"                 mc : Ignorable = "d"                 d : DesignHeight = "300"  d : DesignWidth = "300" >      < Grid >                   </ Grid > </ UserControl > Code Behind: using  System; using  ViewModels; name

C# How to unit test Dispatcher

Dispatcher provides services for managing the queue of work items for a thread. Sometimes to execute a task on a background thread.  Any task executed by calling Dispatcher.BeginInvoke(...) in unit test does not get executed until you do some wire-up. This is how you would unit test code with Dispatcher. using  System; using  System.Windows.Threading; using  Microsoft.VisualStudio.TestTools.UnitTesting; namespace  UnitTesting.Tests {     [ TestClass ]      public   class   DispatcherUtilTest     {          private   ClassThatUsesDispatcher  _subject;         [ TestInitialize ]          public   void  TestInitialize()         {             _subject =  new   ClassThatUsesDispatcher ();         }         [ TestMethod ]          public   void  UseDispatcher()         {              // Arrange              var  backgroundWorkDone =  false ;             _subject.BackgroungWorkAction = () => { backgroundWorkDone =  true ; };              // Act             _subject.DoWork(
