[Qemu-devel] [PATCH] iotests: Add more "skip_if_unsupported" statements to the python tests

[Qemu-devel] [PATCH] iotests: Add more "skip_if_unsupported" statements to the python tests

[Thomas Huth]

The python code already contains a possibility to skip tests if the
corresponding driver is not available in the qemu binary - use it
in more spots to avoid that the tests are failing if the driver has
been disabled.

It’s clear that none of these tests can run if there is no quorum
support, because setUp() creates a quorum node.  I think it would be
nice if it would suffice to just skip everything automatically if
setUp() is skipped and not have to bother about each of the test cases.

Coincidentally (:-)), I have a patch to do that, namely “iotests: Allow
skipping test cases” in my “iotests: Selfish patches” series:

https://lists.nongnu.org/archive/html/qemu-block/2019-06/msg01106.html

Yes, that means you cannot use an annotation because it needs @self to
be able to skip the test.  Hm... But I think I can make that work by
simply s/case_notrun/args[0].case_skip/ in skip_if_unsupported()?

Sure, feel free to ignore my patch here or to modify it according to
your reworks. As long as we finally get the iotests into a shape where
they are a little bit more flexible wrt the enabled/disabled drivers,
I'm happy.

Oh, no, I don’t mean to ignore the patch.  I just think that a
skip_if_unsupported() annotation above setUp() should be enough to skip
all tests.

Based on the Max's series "iotests: Selfish patches",
this '+' suffice for the whole methods of the class.
So, I can confirm after testing it.
