'Prevent all python unittests from running based on environment variable

Is there a way I could prevent all unit tests from running if a certain environment variable is not set to a specific value?

For example I want tests to only run if os.getenv(DB_URL) returns sqlite:///:memory:.

I'd like to configure this globally so I don't need to review every single test class / setup function to check this individually.

There's many ways to accomplish this, but a fixture is probably the easiest

import os
import pytest

DB_URL = "foo"

@pytest.fixture(autouse=True, scope="session")
def verify_db_url():
    expected_url = "sqlite:///:memory:"
    if os.getenv(DB_URL) != expected_url:
        pytest.exit("Exiting due to incorrect database environment variable.")
