After you install one of the supported Visual Studio 2008 editions, you will get a menu item called “Test” in your Visual Studio menu bar.
Open Visual Studio and make sure you can see a menu item called “Test” in the menu bar. If you do not see the “Test” menu, it indicates that you do not have appropriate edition of Visual Studio which supports unit testing.
If you expand the “Test” menu, it shows the sub menu items as shown in the picture below.
The first sub menu is “New Test”. This option allows you to create new Tests. If you click on “New Test” you will get several options including Unit Test, Load Test, Web Test etc. I will explain them later.
