Nose indeed has some problems with test generators in classes inherited
from TestCase. This is probably a bug in Nose.
If you don't need the self.* methods available in a 'TestCase' class, you
can base the class on 'object' instead. Nose still finds the tests in it,
and the generators start to work.

I think it will work if the decorators are applied to the _check methods
instead. But this seems like a bug in Nose -- it should catch SkipTest
raised already in the generator method, not only in functions yielded by
