Pytest doesn't seem to recognize and run my tests

So the previous answer to this question doesn't seem to work for me. But I think this problem has something to do with my package references or my setup.cfg file.

I have two tests (just to start with to try and get this working) the results are:

================================ test session starts ==================================================================================================================================================================

    self._warn_or_fail_if_strict("Unknown config option: {}\n".format(key))

-- Docs: https://docs.pytest.org/en/stable/warnings.html
================================ 1 warning in 0.61s ===================================================================================================================================================================

Now my setup.cfg file is:

current_version = 0.1.0
commit = True
tag = True

[bumpversion:file:setup.py]
search = version='{current_version}'
replace = version='{new_version}'

[bumpversion:file:geo_calcs/__init__.py]
search = __version__ = '{current_version}'
replace = __version__ = '{new_version}'

[bdist_wheel]
universal = 1

[flake8]
exclude = docs
[tool:pytest]
collect_ignore = ['setup.py']

My test cases all seem to be named correctly. Here is an example:

from geo_calcs.calculations.geochem import *

@pytest.fixture
def test_get_atomic_weight():
    assert get_atomic_weight(["Si","O","O"]) == 60.0843

Finally my directory structure is:

Does anyone have any insight?

Remove the @pytest.fixture decorator from above the test. Tests shouldn't have that, they're discovered by naming convention.

Pytest uses glob-style name patterns to collect tests, and the discovery can be customized by the options python_files, python_classes, and python_functions in the configuration file.

The default patterns are:

[pytest]
python_files=test_*.py
python_classes=Test*
python_functions=test_*
