Unit Testing

(myenv) pip freeze > requirements.txt

Test endpoint (no server needed).

If running from the root still gives issues, add a pytest.ini at the project root:

 
# D:\python-apps\fastapi-service\pytest.ini
[pytest]
testpaths = tests
pythonpath = .

(myenv) pytest -q
(myenv) python -B -m pytest

Test the live UAT URL (like a PHP snippet)
