In Cartopy, we have some parameterized tests that create a figure, try to do some things on that figure in a try/except clause, and if it hits the exception throw a pytest.skip() to indicate we want to skip that test. In the recent 0.16 release, this no longer works and the images are compared and produce a failure due to their being no image to compare against (since we want it skipped).
