Pytest 3.7 not collecting tests on mixed Package and Modules #3768
Description
Hi!
I've found an issue with pytest 3.7 while collecting tests on a mixed Python packages and modules folder structure, which worked correctly on previous versions of pytest. For instance if I setup a folder structure like this:
.
└── src
├── folder_1
│ └── test
│ └── test_1.py
└── folder_2
└── test
└── test_2.py
Each test_*.py file containing a dummy test like:
def test_1():
assert True
pytest collects tests correctly:
$ py.test --collect-only
=========================================================================================== test session starts ============================================================================================
platform darwin -- Python 2.7.10, pytest-3.7.0, py-1.5.4, pluggy-0.7.1
rootdir: /Users/eduardo/tests, inifile:
collected 2 items
<Module 'src/folder_1/test/test_1.py'>
<Function 'test_1'>
<Module 'src/folder_2/test/test_2.py'>
<Function 'test_2'>
======================================================================================= no tests ran in 0.05 seconds =======================================================================================
However if I convert one of the folders to a Python package, only the tests inside that folder are being collected:
.
└── src
├── __init__.py
├── folder_1
│ ├── __init__.py
│ └── test
│ └── test_1.py
└── folder_2
└── test
└── test_2.py
$ py.test --collect-only
=========================================================================================== test session starts ============================================================================================
platform darwin -- Python 2.7.10, pytest-3.7.0, py-1.5.4, pluggy-0.7.1
rootdir: /Users/eduardo/tests, inifile:
collected 1 item
<Package '/Users/eduardo/tests/src'>
<Package '/Users/eduardo/tests/src/folder_1'>
<Module 'test_1.py'>
<Function 'test_1'>
======================================================================================= no tests ran in 0.03 seconds =======================================================================================
I'm not pretty sure if this is the intended behaviour or not.
Debugging info:
pip list (fresh venv tested with python2.7 and 3.6 with same results)
