Streamline test skipping based on supported features This adds a new test decorator: skip_unless_feature(). The argument is the same as passed to features.check(). If the feature is not supported, the test will be skipped. This removes several kinds of boilerplate copied and pasted around tests so test feature checking is handled and displayed more consistently. Refs #4193 2020-02-18 01:03:32 +03:00			`from PIL import Image`
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
