Matt Riedemann 5b3a827a1f Provide stderr in exception when check_parser fails ... For negative tests that are asserting an argparse failure it would be useful to assert the specific reason for the failure in the test rather than just getting an exception, especially to avoid false positives in the tests when what is being tested and failing isn't the actual expected reason for the failure. This wraps the check_parser code that parses the args and mocks sys.stderr so we can trap that output and put it in the exception message that gets raised to the test. As a result, we can tighten up a test that was passing before for the wrong reason [1].
