Although I think it's good to test with different configurations, where not
all tests pass. Because then there's times when a test will fail when it
should have been ignored, and that will let us know that there's a bug in
the test.

Or, different configurations might make a test fail that should have
passed, where a missing dependency was made.

I had someone report a bug that I never caught because it only happened
when something was configured off, and because I tested with everything on,
I never hit that bug.
