How to suppress the `RemovedInDjango40Warning` warnings in a unit test?

Using Django Forms & APIs
1

We are working on a unit test in PyCharm and the test itself is passing now. However, the terminal output contains warning messages in the RemovedInDjango40Warning category. As we do not plan to upgrade to Django 4.0 for now, these warnings are verbose and distracting.

We tried including the statement warnings.simplefilter("ignore", category=RemovedInDjango40Warning) but it did not suppress the warnings.

So, we wonder how to suppress the RemovedInDjango40Warning warnings.

Technical Details:

Partial source code of the unit test:
from unittest import TestCase

import Django


class TestPocFunctional(TestCase):
    @classmethod
    def setUpClass(cls):
        django.setup()
        return

    def test_all(self):
        from application.poc import PocFunctional
        import warnings
        from django.utils.deprecation import RemovedInDjango40Warning
        warnings.simplefilter("ignore", category=RemovedInDjango40Warning)
        
        # ... testing steps
        
        return
The terminal output of warnings:

I might try making these a “global” setting by either putting them outside the class in that module or making them entries in your settings.py file.

Changed the unit test to the sample code below, and unfortunately, the warnings are still coming out in the terminal output.

So, we are still looking forward to more hints and suggestions.

from unittest import TestCase

import Django

import warnings
from django.utils.deprecation import RemovedInDjango40Warning
warnings.simplefilter("ignore", category=RemovedInDjango40Warning)


class TestPocFunctional(TestCase):
    @classmethod
    def setUpClass(cls):
        django.setup()
        return

    def test_all(self):
        from application.poc import PocFunctional
        import warnings
        from django.utils.deprecation import RemovedInDjango40Warning
        warnings.simplefilter("ignore", category=RemovedInDjango40Warning)
        
        # ... testing steps
        
        return
