Hey folks, I am moving multiple django microservices into a pants monorepo, so far I managed to get

runserver

working. Next is to get my tests working. So, any chance of getting my existing `APITestCase`s to run without a change? Running

./pants run src/python/worker/manage.py -- test

results in 0 discovered tests. If I specify the tests target

./pants run src/python/worker/manage.py -- test src/python/worker/app/tests

I get

No module named 'worker.app.tests'

I checked both the django sample and the django webinar, but unfortunately this project is running using pytest, and my microservices are not. nevertheless I tried running

./pants test src/python/worker/app/tests/test_api.py

but I think it won't work out of the box, I got the following:

Copy code

django.core.exceptions.ImproperlyConfigured: Requested setting REST_FRAMEWORK, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

What is is the shortest path to get my tests running?

Make sure you turn on the

string_imports

under

python-infer

option which will perhaps help pants infer deps from django strings used to specify python modules (apps, middleware, etc...) https://www.pantsbuild.org/docs/reference-python-infer#string_imports

you can also use the

dependencies

goal to see which deps pants is able to infer. For example

./pants dependencies src/python/worker/manage.py

or ``./pants dependencies src/python/worker/app/tests/test_api.py``

those will show direct dependencies, if you want to see transitive deps add the

--dependencies-transitive

option

string_imports

is enabled manage.py and tests/* don't have any dependency on each other. I tried to set some dependencies manually and got weird errors. Any recommendation?

I added

Copy code

python_tests(
    name="tests0",
    dependencies=[
        "src/python/worker:worker",
    ],
)

to my tests BUILD and now manage.py is showing as dependency, but still same DJANGO_SETTINGS_MODULE problem

I got them running by configuring pytest and conftest.py as per the github example, but everything is failing. One step closer!

@glamorous-nail-59544 Just curious if you figured it out. I ran into the same issue where the pytest vscode extension picked up the tests when `DJANGO_SETTINGS_MODULE`is set, but pants couldn't find the module.

@tall-plastic-15186 yes I have it running now. As mentioned before, following pytest configs here made it work, and tests were failing due to misconfigured assets dependencies.
