python - Py.test fixture: Use function fixture in scope fixture -

i facing small issue pytest fixtures, appreciate help.

i have few function fixtures mentioned below. simplicity have not show implementation.

@pytest.fixture() def get_driver():     pass  @pytest.fixture() def login(get_driver):     pass  @pytest.fixture() def settings(login):     pass 

the problem need 1 more (session level) fixture setup before run first test case. (actually start testing). i.e. go settings page , create few settings. (after login)

now problem can't using session level fixture, can't use function level fixture in session level. or can i?

@pytest.fixture(scope="session") def setup(settings):     settings.create_settings()     pass 

you need use workaround. action needs done in function scoped fixture autouse set true.

you need initialize variable in session based fixture, check if settings have been done or not. if not done, settings , change flag false

below working example

import pytest   @pytest.fixture(scope="session", autouse=true) def settings_page():     config = {"config_done": false}     return config   @pytest.fixture() def init(request):     print("init called")     return "init"   @pytest.fixture() def driver():     print("driver called")      return "driver"   @pytest.fixture(autouse=true) def init_settings(settings_page, driver):     if not settings_page["config_done"]:         print("settings being done first time")         settings_page["config_done"] = true   @pytest.fixture() def login():     print("login called")     return "login"   @pytest.fixture() def logged_in_driver(init, driver, login):     print("logged in driver ready")     return (init, driver, login)   @pytest.fixture() def non_logged_in_driver(init, driver):     print("non logged in driver ready")     return (init, driver)   def test_1(logged_in_driver):     print("test_1")   def test_2(non_logged_in_driver):     print("test_2") 

output below

test.py driver called settings being done first time init called login called logged in driver ready .test_1 driver called init called non logged in driver ready .test_2 

so can see settings happens once
