[New-bugs-announce] [issue9554] test_argparse.py: use new unittest features

[Denver Coneybeare]

New submission from Denver Coneybeare <denver.coneybeare at gmail.com>:

Some of the unit testing code in test_argparse.py could be modified to take advantage of the new unittest features in Python 2.7 and 3.x.  My suggested changes are attached in the patch file test_argparse.py.unittest2.patch

One big one is that assertEquals() now prints a "diff" when multi-line strings compare unequal, so the manual "diffing" logic from the unit tests can be removed.  Also, assertIsNone() is slightly better than assertEquals(None, x).  Finally, there is a tiny fix where parse_args() was expected to throw ArgumentParserError but the test would not fail if it threw no exceptions.
