Allow for overriding of pytest fixture scope about pytest-docker HOT 5 CLOSED

Having scope=module on the other hand is useful to run a battery of tests against a set of environments defined in the same file. At least it's a better fit for my use case, otherwise I have to run pytest multiple times.

@mmetc in that case, it'd be better to allow the flag to be set to the desired scope directly, so something like

def pytest_addoption(parser):
    parser.addoption(
        "--containers-scope",
        type=str,
        default="function"
        help="The pytest fixture scope for reusing containers between tests. For available scopes and descriptions, see https://docs.pytest.org/en/6.2.x/fixture.html#fixture-scopes",
    )


@pytest.fixture
def containers_scope_fixture(request):
    return request.config.getoption("--containers-scope")


def containers_scope(fixture_name, config):
    return config.getoption("--containers-scope-fixture", "function"):


@pytest.fixture(scope=containers_scope)
# This annotation can apply to all fixtures, instead of the hard-coded "session" scope

That is true, but sometimes I need different compose.yaml configs for different set of tests. If I haven't got different scopes, I need to run pytest for each set of tests needing the same docker-compose yaml.

I would've expected a function scope to be the default, are there any blockers to implementing this?
