py3k: Import Christoph Gohlke's test suite This is Christoph Gohlke's test suite from his personal PIL package found at http://www.lfd.uci.edu/~gohlke/pythonlibs/. This is just to bring it in as a separate commit. Future commits will align it with Pillow. 2012-10-16 00:26:38 +04:00

Remove unnecessary unittest.main() boilerplate from test files With the introduction and use of pytest, it is simple and easy to execute specific tests in isolation through documented command line arguments. Either by specifying the module path or through the `-k EXPRESSION` argument. There is no longer any need to provide the boilerplate: if __name__ == '__main__': unittest.main() To every test file. It is simply noise. The pattern remains in test files that aren't named with `test_*` as those files are not discovered and executed by pytest by default. 2019-02-03 18:34:53 +03:00			`pytest Tests/test_image.py`
