summary:

bpo-34279: regrtest consider that skipped tests are ran (GH-11132)


bpo-34279, bpo-35412: support.run_unittest() no longer raises
TestDidNotRun if a test result contains skipped tests. The
exception is now only raised if no test have been run and no test
have been skipped.
(cherry picked from commit 3a8f4fef4a4dd0e4a800545468eef9542e126181)
