Run Code After All Fixtures but Before Test

[cancan101]

Is there some way to run certain code after all the fixtures have been created but before the test code itself is run?

For example I have a number of fixtures that create DB objects and would like to call commit() after they are created but before the test itself is run. I could just call commit at the end of each fixture but that slows down the test set up.

One thing you could do is have a fixture what depends on the other ones:

import pytest


@pytest.fixture
def create_a():
    print("create a")


@pytest.fixture
def create_b():
    print("create b")


@pytest.fixture
def db_objects(create_a, create_b):
    print("committing")


def test_db(db_objects):
    pass

If you wanted the db to be prepared like that for all tests, you could also make db_objects autouse.

I would like to avoid having to list all of the dependent fixtures for a couple reasons:

• Different tests will have different requirements
• There are many, many fixtures and keeping the list up to date would be a challenge

autouse sounds interesting, but when would it run? ie would it run or after other fixtures? Or unspecified?

I believe that a runtest_setup trylast hook with some terrifying magic is necessary to sort this stuff out
