Two tests fail when warnings are present in the test run

[koobs]

The following two tests fail if there are any warnings in the test run:

test_shows_tests_nested_under_classes_without_files
test_tests_are_colorized_by_test_result

with failure output:

>           assert "== 1 failed, 4 passed, 1 skipped in " in output
E           AssertionError: assert '== 1 failed, 4 passed, 1 skipped in ' in '============================= test session starts ==============================\nplatform freebsd13 -- Python.../en/latest/warnings.html\n========== 1 failed, 4 passed, 1 skipped, 1 warnings in 0.28 seconds ==========='

=================================== FAILURES ===================================

self = <other_behaviors.OtherBehaviors instance at 0x80467f9e0>

    def behavior_four(self):

E       AssertionError

other_behaviors.py:13: AssertionError

========== 1 failed, 4 passed, 1 skipped, 1 warnings in 0.28 seconds ===========

I tried --disable-warnings for the test run, but this may not (it seems?) apply to captured output.

Tests should account either for the possibility of X warnings in the output, or ignore warnings by removing in from the test string assertion

The following patch fixes the issue for me, if you decide you want to go that way (ignoring warnings, rather than accounting for them):
