Subject: bpo-36674: Honour the skipping decorators in TestCase.debug() (GH-28446)
X-Git-Tag: v3.11.0a1~125
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dea59cf88adf5d20812edda330e085a4695baba4;p=thirdparty%2FPython%2Fcpython.git

bpo-36674: Honour the skipping decorators in TestCase.debug() (GH-28446)

unittest.TestCase.debug() raises now a SkipTest if the class or
the test method are decorated with the skipping decorator.

Previously it only raised a SkipTest if the test method was decorated
with other decorator in addition to the skipping decorator, or
if SkipTest was explicitly raised in the test or setup methods.
