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.
