Exclude a list of tests with py.test but on the command line?

Question

I would like to exclude a list (about 5 items) of tests with py.test.

I would like to give this list to py.test via the command line.

I would like to avoid to modify the source.

How to do that?

Answer 1

You could use tests selecting expression, option is -k. If you have following tests:

def test_spam():
    pass

def test_ham():
    pass

def test_eggs():
    pass

invoke pytest with:

pytest -v -k 'not spam and not ham' tests.py

you will get:

collected 3 items

pytest_skip_tests.py::test_eggs PASSED             [100%]

=================== 2 tests deselected ===================
========= 1 passed, 2 deselected in 0.01 seconds =========
