Some of the unit testing code in 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

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.

These all look like good changes to me. (I looked at the patch, but haven't tried applying it though.)

Hi, I've applied the patch and it goes fine (except for some offsets and the fact it was generated inside Lib/test) and the tests are still all ok. I'd suggest to apply it.

The patch is still valid - it applies ok. The only issues as mentioned by sandro.tosi are offsets and that it was generated inside Lib/

It would be worth having these changes applied.

Another one:

         except ArgumentParserError:
             err = sys.exc_info()[1]

This reeks of single-codebase-for-2.x-and-3.x and could probably be replaced by assertRaises or at least a regular

Hi Eric, Denver's patch should apply correctly from the root. Also, I've made the changes you mention:

try: except: assert

has been replaced by:

with self.assertRaises()
