Actual behaviour

In main tests/ directory are some tests and some other files needed. Those work fine until a subdirectory is created, which contains 2 tests named test_decorators.py and test_pagination.py, this subdirectory also contains the __init__.py so that the tests can be recognized. After this subdirectory is created, the tests from main directory (tests/) disappear and the ones from subdirectory are not displayed either, a popup saying that no tests were discovered and asking me to configure the test framework (It is configured properly)

Once the __init__.py file is added and I rediscover the tests, this box pops up.

Expected behaviour

When I add the subdirectory to main tests/ directory and search for the tests, both the tests from my main directory and the subdirectory should be found.

Steps to reproduce:

1. Create directory for tests in root of your project tests/
2. Configure the framework to use unittests and recognise files labeled: test_*.py
3. Add some tests in it and let the framework discover them [To this point everything is as expected]
4. Add a subdirectory in your tests/ directory and place some other tests in it
5. Run test discovery again
6. No tests were found
