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			`from .helper import PillowTestCase, hopper`
fix 2.6 tests by replacing usages of deprecated fromstring/tostring with frombytes/tobytes 2013-02-26 14:28:34 +04:00
			`from PIL import Image`


Convert old tests to use unittest 2014-06-10 13:10:47 +04:00			`class TestImageFromBytes(PillowTestCase):`
			`def test_sanity(self):`
Replace some lena() with hopper(), and temporarily disable fail-fast so we can see all failures 2014-09-05 14:03:56 +04:00			`im1 = hopper()`
Convert old tests to use unittest 2014-06-10 13:10:47 +04:00			`im2 = Image.frombytes(im1.mode, im1.size, im1.tobytes())`
