Test if code is executed from within a py.test session

Question

I\'d like to connect to a different database if my code is running under py.test. Is there a function to call or an environment variable that I can test that will tell me i

Answer 1

There's also another way documented in the manual: https://docs.pytest.org/en/latest/example/simple.html#pytest-current-test-environment-variable

Pytest will set the following environment variable PYTEST_CURRENT_TEST.

Checking the existence of said variable should reliably allow one to detect if code is being executed from within the umbrella of pytest.

import os
if "PYTEST_CURRENT_TEST" in os.environ:
    # We are running under pytest, act accordingly...
