6.1 Unit testing
The testing procedure described here assumes you are using the NUnit test tool. You can download the NUnit user interface and libraries fromhttp://www.NUnit.org. This web page also gives more information about NUnit. Basically, you create a test class for each of the wrapper classes; in the test classes you implement a test method for each public method in the class.

As described earlier, the model is migrated by implementing the IEngine interface. For every IEngine method in the MyEngineWrapper class you decide which method needs to be implemented in the remaining wrapper classes. You will implement the methods or functions that are needed in the engine core and then implement the corresponding methods in the MyEngineDLLAccess class and MyEngineDotNetAccess class. Each time you have
completed the implementation of a method you can create a test method in the MyEngineDotNetAccessTest class and run the unit test. You can then move on to implement the method in MyEngineAccess and the associated test methods.
