Completely nerding out about pytest markers with Anthony Sottile.
Some of what we talk about:
- Running a subset of tests with markers.
- Using marker expressions with and, or, not, and parentheses.
- Keyword expressions also can use and, or, not, and parentheses.
- Markers and pytest functionality that use mark, such as parametrize, skipif, etc.
- Accessing markers with itermarkers and get_closest_marker through item.
- Passing values, metadata through markers to fixtures or hook functions.
