Running tests in parallel breaks when using absolute path to SQLite database #1008

Open icemac opened 2 years ago

icemac commented 2 years ago

What I did

Ran tests of a Django project using tox -p – so TOX_PARALLEL_ENV is set to true.
I set the path to the SQLite database to be used as absolute path.

What I expected

Successful run in parallel for the different tox environments.

What actually happened

pytest-django changed the path to the database file while breaking the path.
Example: database name /home/user/project/my-project.sqlite in tox env py39 caused that the database name is changed to test_/home/user/project/my-project.sqlite_py39 which is not a valid path on user's hard disk.

Suggestion

Check for (absolute) paths in https://github.com/pytest-dev/pytest-django/blob/f27c6aa1d44beb46fefa4718fefcf541478643d7/pytest_django/fixtures.py#L281 and handle it appropriately.
