Writing Conformance Tests

[Mike]

Being new to wine, I was thinking about starting to learn the system by writing conformance tests.

Most of us do NOT have access to machines of every flavor of Windows.  Is there a standard method to deal with differences across platforms?

I realize that often, this won't be an issue, but was wondering what (if any) the practice is for write across platforms without access to these platforms.

Thanks,
