# helper module for test_runner.Test_TextTestRunner.test_warnings
|
|
|
|
"""
|
|
This module has a number of tests that raise different kinds of warnings.
|
|
When the tests are run, the warnings are caught and their messages are printed
|
|
to stdout. This module also accepts an arg that is then passed to
|
|
unittest.main to affect the behavior of warnings.
|
|
Test_TextTestRunner.test_warnings executes this script with different
|
|
combinations of warnings args and -W flags and check that the output is correct.
|
|
See #10535.
