pytest marks

what is it?

A way to add meta data to tests

skip a test

import pytest
 
@pytest.mark.skip
def test_example():
	assert 1 == 1

mark a test that is a known failure

import pytest
 
@pytest.mark.xfail
def test_example():
	assert 1 == 2

custom markers

• edit pytest.ini

  [pytest]
  DJANGO_SETTINGS_MODULE = fica_face.settings
  # define where tests are collected from
  python_files = test_*.py *_tests.py
  markers = 
  	slow: slow running tests

• mark test as slow

  import pytest
   
  @pytest.mark.slow
  def test_example():
  	assert 1 == 2

• only run slow tests: pytest -m "slow"

• skip slow tests: pytest -m "not slow"

database access

• @pytest.mark.django_db

repeat test with different parameters

@pytest.mark.parametrize("result, msg", [
	(False, "dummy msg"),
	(True, "dummy msg")
])
def test_example(result, msg):
	resp = method_to_test()
 
	assert resp == (result, msg)

skipif

skip test if python version is below 3.3:

@pytest.mark.skipif(sys.version_info < (3, 3), reason='does not support XXX')
def test_abc():
    pass
