More on this since I keep seeing patches like this one that
make the reporting confusing.

There is a reason why you don't want to mark a test passed
when there are several skips. Skips are an indication that
there are several tests and/or test cases that couldn't not
be run because of unmet dependencies. This condition needs
to be investigated to see if there are any config options
that could be enabled to get a better coverage.

Including skips to determine pass gives a false sense security
that all is well when it isn't
