caplog

caplog.record_tuples is nice and simple with the caplog fixture:

def test_handler(caplog):
    response = handler(
        APIException("Patrick does not know..."), {"colour": "Green"}
    )
    assert [
        (
            "api.models",
            logging.ERROR,
            "Patrick does not know... {'colour': 'Green'}",
        )
    ] == caplog.record_tuples

freezegun

To use freezegun as a context manager,

pip uninstall pytest-freezegun
pip install freezegun

from freezegun import freeze_time

with freeze_time("2017-05-21"):
    UserConsent.objects.set_consent(consent, True, user_1)
    UserConsent.objects.set_consent(consent, False, user_2)

Or use a date/time:

import pytz
from datetime import datetime
with freeze_time(datetime(2017, 5, 21, 21, 30, 0)):

pytest-freezegun

Warning

I had some issues with pytest-freezegun , but I think the problem was that I had not included it in requirements/ci.txt. I prefer to use the context manager with freezegun, so the following notes are just for information…

https://github.com/ktosiek/pytest-freezegun

@pytest.mark.freeze_time("2017-05-21")
def test_report():

Markers

To register a marker e.g:

@pytest.mark.elasticsearch

Create a conftest.py file e.g. dash/tests/conftest.py or example_crm/tests/conftest.py and add the following:

# -*- encoding: utf-8 -*-
def pytest_configure(config):
    config.addinivalue_line(
        "markers", "elasticsearch: enable or disable tests using elasticsearch"
    )

For more information, see Registering marks.

Tip

This doesn’t seem to work using setup.cfg or pytest.ini (I had problems with configurations being ignored).

Skip

To find out why tests are skipped:

pytest -rsx app/tests/test_app.py
