Feature request: skipping a test from within a test

[whot]

I'd like something like ck_skip() that skips the currently running test. Usage would be:

START_TEST(foo)
{
    if (!something)
       ck_skip()

   ...
   ck_assert(...)
}
END_TEST

Obviously a simple return has the same effect, but a ck_skip() macro could log/process the skipped test better, e.g. warn if a test was called multiple times but skipped every time.

I admit this is a niche use-case. I'm using check for libinput and the test suite has a slightly peculiar design. We have test uinput devices and the test suite adds each test for each matching test device. So e.g. a touchpad tapping test is called for all touchpad test devices.

But some of those devices have special run-time properties that we don't necessarily know at test setup time. So what I need is the ability to skip from within and some way to access that information afterwards. I want to check if a test was skipped for every test device, because then there's some other bug somewhere. Example again: if I test for right buttons on touchpads, I want to skip this on touchpads that don't have right buttons. But if the test always skips, I either have wrong test devices or something else is buggy.

Not 100% how this would look like from check's perspective though, but let's see if this is something wanted/possible at all. If not, that's fine, I agree that this is a bit of a special case :)
