Introduce isort to automate import ordering and formatting Similar to the recent adoption of Black. isort is a Python utility to sort imports alphabetically and automatically separate into sections. By using isort, contributors can quickly and automatically conform to the projects style without thinking. Just let the tool do it. Uses the configuration recommended by the Black to avoid conflicts of style. Rewrite TestImageQt.test_deprecated to no rely on import order. 2019-07-06 23:40:53 +03:00			`from PIL import ImageQt`

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`
Improve pytest configuration to allow specific tests as CLI args The previous test configuration made it difficult to run a single test with the pytest CLI. There were two major issues: - The Tests directory was not a package. It now includes a __init__.py file and imports from other tests modules are done with relative imports. - setup.cfg always specified the Tests directory. So even if a specific test were specified as a CLI arg, this configuration would also always include all tests. This configuration has been removed to allow specifying a single test on the command line. Contributors can now run specific tests with a single command such as: $ tox -e py37 -- Tests/test_file_pdf.py::TestFilePdf.test_rgb This makes it easy and faster to iterate on a single test failure and is very familiar to those that have previously used tox and pytest. When running tox or pytest with no arguments, they still discover and runs all tests in the Tests directory. 2019-01-13 20:00:12 +03:00			`from .test_imageqt import PillowQPixmapTestCase`
