Odd Unit Test Behavior

[ichabod801]

I have this program:

"""
_test_all.py

Overall unit testing for the t_games project.
"""

import unittest

if __name__ == '__main__':
	test_suite = unittest.defaultTestLoader.discover('.', pattern = '*_test.py')
	unittest.TextTestRunner(verbosity = 1).run(test_suite)

This is in a folder with a bunch of other test code files. When I run it, I get two errors in the file interface_test.py:

Output:
======================================================================
ERROR: testAliasStatsTitle (t_games.t_tests.interface_test.InterfaceDoStatsTest)
Test call arguments for Interface.do_stats for a specific game alias.
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\Users\Craig\Documents\t_games\t_tests\interface_test.py", line 184, in testAliasStatsTitle
    self.assertIn('\nUnit Statistics\n', self.bot.info[0])
IndexError: list index out of range

======================================================================
FAIL: testAliasStatsAllGames (t_games.t_tests.interface_test.InterfaceDoStatsTest)
Test stat groups shown for Interface.do_stats for a specific game alias.
----------------------------------------------------------------------
Traceback (most recent call last):
  File "C:\Users\Craig\Documents\t_games\t_tests\interface_test.py", line 179, in testAliasStatsAllGames
    self.assertEqual(1, len(self.bot.info))
AssertionError: 1 != 0

Note that self.bot is a dummy class, that stores any text sent to it in the info attribute. Normally this text would be sent to a class that would print the text. So I'm testing printing some text, and it appears to not be printing.

So I next run interface_test.py, because the full _test_all.py takes a half hour or more. The idea being to work on the problem, rerunning itnerface_test.py as I go to check on my progress, and then rerunning the full _test_all.py at the end to confirm the problem is solved.

The problem is that when I run interface_test.py, the tests don't cause an error. I'm running both programs from the same location using the command line: python t_games\t_tests\_test_all.py or python t_games\t_tests\interface_test.py. I've been running the tests in 2.7 (t_games is designed to be 2.7 and 3.x compatible). I just started the full run in 3.6 to see if I get the same issue there.

Any ideas as to the discrepancy?

Edit: All tests are running fine in 3.6.3, whether I run _test_all.py or interface_test.py. Ha! Unsupported for less than 24 hours and it's already causing me problems. : )
