Serhiy Storchaka bedce3538c [3.10] bpo-45229: Remove test_main in many tests (GH-28405) (GH-28455) ... Instead of explicitly enumerate test classes for run_unittest() use the unittest ability to discover tests. This also makes these tests discoverable and runnable with unittest. load_tests() can be used for dynamic generating tests and adding doctests. setUpModule(), tearDownModule() and addModuleCleanup() can be used for running code before and after all module tests. (cherry picked from commit 40348acc18)		2021-09-19 22:36:03 +03:00
