How to use dynaconf in pytest when declared custom settings object

[mzebrak]

Hi. I need to override the environment for settings in conftest.py. As I found I can do it by adding:

from dynaconf import settings


@pytest.fixture(scope="session", autouse=True)
def set_test_settings():
    settings.configure(FORCE_ENV_FOR_DYNACONF="testing")

but in my case I' ve got my own settings object under in the confg.py module and it looks like this:

settings = Dynaconf(
    envvar_prefix='MY_PREFIX',
    settings_files=['settings.toml', '.secrets.toml'],
    environments=True,
    env_switcher='ENVIRONMENT_NAME',
)

and when I'm trying to do

from config import settings


@pytest.fixture(scope="session", autouse=True)
def set_test_settings():
    settings.configure(FORCE_ENV_FOR_DYNACONF="testing")

it does not work. It only overrides settings imported directly from dynaconf module. This is a problem because in my app I'm using settings from my config.py and my tests are failing when I override settings from dynaconf and use from dynaconf import settings in tests - because in app I'm using from config import settings
