Answer 1

Is your test correctly written? Normally, tests start with test_? But anyway, it depended on what you try to filter, you can filter those tests by name using -k "not slow and not long" or by tag using -m "not slow and not long".

Run tests by keyword expressions

-k: This will run tests which contain names that match the given string expression (case-insensitive), which can include Python operators that use filenames, class names and function names as variables.

Run tests by marker expressions

-m: Will run all tests which are decorated with the @pytest.mark.slow decorator.
