Python Testing with pytest

Using Multiple Fixtures

You’ve already seen that tmpdir uses tmpdir_factory. And you used tmpdir in our tasks_db fixture. Let’s keep the chain going and add some specialized fixtures for non-empty tasks databases:

ch3/a/tasks_proj/tests/conftest.py

@pytest.fixture()
def db_with_3_tasks(tasks_db, tasks_just_a_few):
    """Connected db with 3 tasks, all unique."""
    for t in tasks_just_a_few:
        tasks.add(t)


@pytest.fixture()
def db_with_multi_per_owner(tasks_db, tasks_mult_per_owner):
    """Connected db with 9 tasks, 3 owners, all with 3 tasks."""
    for t in tasks_mult_per_owner:
        tasks.add(t)

These fixtures all include two fixtures each in their parameter list: tasks_db and a data set. The data set is used to add tasks to ...
