Fixtures

Last updated:
Reference:docs.pytest.org

Usage ​

The tests configuration file is named conftest.py. It is placed inside the tests folder.

Test fixtures ​

Can be used as parameters in each test.

python
import pytest

@pytest.fixture
def some_list():
    return [1, 2, 3]

# Example of how to use
def test_something(some_list):
    assert somelist == [1, 2, 3]

Session fixtures ​

To run some code only once before all tests (for DB setup, for example), use scope='session', autouse=True.

python
@pytest.fixture(scope='session', autouse=True)
def setup_session():
    setup_database()
    yield
    teardown_database()

autouse applies the fixture automatically.
