A fixture which gives access to all databases in tests

[dferens]

Hi,

At my company we have a problem that we have to use mark on every test:

@pytest.mark.django_db(databases="__all__")
def test_something(db):
   ...

@pytest.mark.django_db(databases="__all__")
def test_other(db):
    ...

# + a bunch of tests which needs to be marked as well

I'd like to propose a solution:

def setup_db(db, django_db_all_databases):
    pass

def test_something(setup_db):
    ...

def test_other(setup_db):
    ...

Let me know what you think. If you approve this, I will improve this PR with tests, docs, docstrings and so on. I wanted to know your opinion first.

Thanks!

Hey, can anyone look into this?

I would not want to merge something like this since it encourages a bad practice. So my suggestion, if you want to do this, is to put the following in an initial conftest.py file:

import pytest

@pytest.hookimpl(tryfirst=True)
def pytest_collection_modifyitems(items):
    marker = pytest.mark.django_db(databases="__all__")
    for item in items:
        item.add_marker(marker)
