Assignment 7

Unit Testing

Goal: Gain experience in selecting, implementing, and analyzing tests.

Description: Testing beginning with the smallest possible units results in higher quality of the completed product. Developing and executing these tests is a time sink for developers. Semi-automated test tools assist the developer. The dotUnit tool provides the means for rapid development and execution of tests.

Procedure:

1. Download the DotUnit zip file. Install DotUnit.
2. Download the classes under test. Unzip
3. The download includes a .Net project file. Open the project in Visual Studio .NET. Update the project to have a reference to the DotUnit dll. Do this by removing the current reference to DotUnit and then add in a reference to the new location.
4. Select tests to be executed.
5. Write and compile these tests.
6. Use the Windows Explorer to go into the directory where you installed DotUnit. Go into bin/DeBug. There you will find DotUnit.exe. Double click on this and it will run. When it runs you can select which test class for it to use. Choose the one you just compiled. The test class that you compile is not an executable. There is nothing wrong with the installation of Visual Studio or of DotUnit. You must begin execution with DotUnit not with VelocityTest.
7. Observe the results and analyze the results.
8. Add tests based on the previous results.
9. Write-up the results.

Turn-in: The test classes you write or expand. Each test should have a comment that explains why this particular test was selected for execution. An analysis of suspected problems.
