Differences between UsUnit and DUnit and JUnit
Even though UsUnit tries to be similar to JUnit and DUnit it does not always work the same way. This is mostly because of missing features in UnrealScript.
No reflection
UnrealScript doesn't have any (decent) reflection. Because of this TestCases don't work like in DUnit. There's only one entry point per TestCase (e.g. the run() function). In DUnit you can have multiple entry points for the same class, each entry point would have it's own instance. In UsUnit you will simply have to create multiple TestCases and a TestSuite.
No test registration
There is no package initialization code in UnrealScript and no relfection. Therefor it's not possible to find all available tests. There is some code (for UE2.5 only) that can find tests in a package but it's a rather dirty hack. Also it works well when the package is not loaded already.
