Miss Islington (bot) 68ca19061d [3.12] gh-103186: Fix or catch 'extra' stderr output from unittests (GH-103196) (#106605) ... gh-103186: Fix or catch 'extra' stderr output from unittests (GH-103196) Reduce test noise by fixing or catching and testing stderr messages from individual tests. test_cmd_line_script.test_script_as_dev_fd calls spawn_python and hence subprocess.Popen with incompatible arguments. On POSIX, pass_fds forces close_fds to be True (subprocess.py line 848). Correct the call. test_uuid.test_cli_namespace_required_for_uuid3: when the namespace is omitted, uuid.main calls argparse.Argument_Parser.error, which prints to stderr before calling sys.exit, which raises SystemExit. Unittest assertRaises catches the exception but not the previous output. Catch the output and test it. test_warnings.test_catchwarnings_with_simplefilter_error similarly prints before raising. Catch the output and test it. --------- (cherry picked from commit 9d582250d8) Co-authored-by: Ijtaba Hussain <ijtabahussain@live.com> Co-authored-by: Oleg Iarygin <oleg@arhadthedev.net>		2023-07-10 21:03:32 +00:00
