This test is not very clear.

`testProcessCheckPSR0`: what exactly you're testing from PSR0? What you're testing is if the namespace separator is used for nesting the class file in directories. So what about `testProcessUsesNamespaceSeparatorForNestingClassFilesInDirectories`?

The test should have as less things as possible. What you're using is the mondator, and the init definition extension. What do you want the other things for?

You're checking a file in the temp dir. Why are files being generated in the temp dir if you didn't indicate it before?
