How to specify several marks for the pytest command

Question

Reading http://doc.pytest.org/en/latest/example/markers.html I see the example of including or excluding certain python tests based on a mark.

Including:

pytest -v -m webtest

Excluding:

pytest -v -m "not webtest"

What if I would like to specify several marks for both include and exclude?

Answer 1

Use and/or to combine multiple markers, same as for -k selector. Example test suite:

import pytest


@pytest.mark.foo
def test_spam():
    assert True


@pytest.mark.foo
def test_spam2():
    assert True


@pytest.mark.bar
def test_eggs():
    assert True


@pytest.mark.foo
@pytest.mark.bar
def test_eggs2():
    assert True


def test_bacon():
    assert True

Selecting all tests marked with foo and not marked with bar

$ pytest -q --collect-only -m "foo and not bar"
test_mod.py::test_spam
test_mod.py::test_spam2

Selecting all tests marked neither with foo nor with bar

$ pytest -q --collect-only -m "not foo and not bar"
test_mod.py::test_bacon

Selecting tests that are marked with any of foo, bar

$ pytest -q --collect-only -m "foo or bar"
test_mod.py::test_spam
test_mod.py::test_spam2
test_mod.py::test_eggs
test_mod.py::test_eggs2
