Re: [Gdiplus 6/6] Don't check for succeeding functions, they always do

The GetGeneric* functions forward to CreateFontFamilyFrom name; I wrote the regression tests to make sure that we retrieve the correct font; Also, if one fails, it will be caught when the FontName string doesn't compare correctly.

Conformance tests are: * independent of implementation. We don't know how native implements this function (and we don't really care), and there's no guarantee that our implementation of CreateFontFamilyName won't change. * independent of other tests (unit). You're watering down the 'FontName string comparison' test by making it also rely on the results of the previous GetGeneric* functions as well. Each test tests one thing. -- James Hawkins

Ok. I'll scrap this patch.
