It seems your problem is that Windows is not case sensitive when opening files. But its file systems are case preserving so you can overcome this by testing that the case of the file that was loaded is the same as the case of the mixin name. Testing the file name would address the root cause of the problem and avoid dependence on the internals of the mixins.

Retreiving the case of the file isn't elegant, but it is easy enough - just read the directory to find the file name.

But a quick review of the MixinFactory::Factory->class() method, combined with your control over the mixin modules to ensure they have package statements with package names corresponding to their file names suggests that either of your proposed tests should be adequate.
