Hm.. so I think we don't need separate test__skip_subtest().
test__skip() should skip either test or sub-test, depending on which
context we are running in. So maybe just make sure this is handled
correctly?

So because some sub-tests might be skipped, while others will be
running, let's keep output consistent with SUCCESS and use
<test>/<subtests> format for SKIPPED as well?
