Test cases for platforms

[arthrp]

In the request for help it was mentioned that some platforms are basically not tested at all. I'd be interested to help - with testing and possibly some code contributions.
Thus, a question - is there any test set defined for the platforms (especially those in need of testers - like webassembly)? If not, maybe defining some basic test set will help with current situation?

Currently, you add yourself to this list then we ping you when we got changes that need testing: https://github.com/rust-windowing/winit/wiki/Testers-and-Contributors

Alas, their is not exactly a set list of things for people to test. There was some discussion somewhere about writing an interactive test suit, but no ones gotten around to it.
