Useful material on how to deal with slow tests in py.test, a bit buried in the docs:
From http://doc.pytest.org/en/latest/usage.html, to get a list of the slowest 10 test durations:
pytest --durations=10
From http://doc.pytest.org/en/latest/example/simple.html, to skip slow tests unless they are requested:
# content of conftest.py
import pytest
def pytest_addoption(parser):
parser.addoption("--runslow", action="store_true",
help="run slow tests")
# content of test_module.py
import pytest
slow = pytest.mark.skipif(
not pytest.config.getoption("--runslow"),
reason="need --runslow option to run"
)
def test_func_fast():
pass
@slow
def test_func_slow():
pass
Very convenient to know.
