Python Testing with pytest

Using “and,” “or,” “not,” and Parentheses with Markers

We can combine markers and use a bit of logic to help select tests, just like we did with -k keywords in ​Using Keywords to Select Test Cases​.

We can run the “finish” tests that deal with exceptions with -m "finish and exception":

$ pytest -v -m "finish and exception"
========================= test session starts ==========================
collected 12 items / 11 deselected / 1 selected

test_finish.py::test_finish_non_existent PASSED                  [100%]

=================== 1 passed, 11 deselected in 0.01s ===================

We can find all the finish tests that are not included in the smoke tests:

$ pytest -v -m "finish and not smoke"
========================= ...
