plain.pytest

Test with pytest.

Use the plain test command to run tests with pytest and automatically load a .env.test (if available).

Fixtures

Use the settings fixture to access and modify settings during tests.

def test_example(settings):
    settings.DEBUG = True
    assert settings.DEBUG is True

A lightweight wrapper around Playwright that starts a gunicorn side-process to point the browser at.

Note that playwright, pytest-playwright, and gunicorn are not dependencies of this package but are required if you want to use this fixture.

def test_example(testbrowser):
    page = testbrowser.new_page()
    page.goto('/')
    assert page.title() == 'Home Page'

If plain.models is installed, then the testbrowser will also load the isolated_db fixture and pass a DATABASE_URL to the gunicorn process.
