* [3.9] bpo-40173: Fix test.support.import_helper.import_fresh_module() ↵Serhiy Storchaka2021-09-301-42/+27
| | | | | | | | | | | | | | | (GH-28654) (GH-28658) * Work correctly if an additional fresh module imports other additional fresh module which imports a blocked module. * Raises ImportError if the specified module cannot be imported while all additional fresh modules are successfully imported. * Support blocking packages. * Always restore the import state of fresh and blocked modules and their submodules. * Fix test_decimal and test_xml_etree which depended on an undesired side effect of import_fresh_module().

* [3.9] bpo-45229: Remove test_main in many tests (GH-28405) (GH-28456)Serhiy Storchaka2021-09-201-8/+2
| | | | | | | | | | | 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..

| | | | | | | | | | | | | | | (GH-27810) Additional improvements: - messages which were compiled regular expressions aren't unpacked back into strings for unmatched warnings; - removed unnecessary "if tokens:" check (there's one before the for loop); - took `endswith` calculation out of the for loop.

* bpo-37957: Allow regrtest to receive a file with test (and subtests) to ↵Pablo Galindo2019-11-191-12/+38
| | | | | | | ignore (GH-16989) When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored. For these reasons, add a new option to allow to ignore a list of test and subtests for these situations.
