Configure pytest using testpaths to search for tests inside tests folder

Question

I'm trying to improve the test collection speed by including the testpaths option in the pytest.ini file.

Inside each App folder I have a tests file where I put my tests, so I'm including it as follows:

[pytest]
testpaths = tests

However, no tests are collected. It returns the error: ERROR: file or directory not found: tests

What I'm I missing?

Oui

According to the documentation, testpaths is a list of directories that should be searched for tests. I don't think this is what you are providing here. – Damick

testpaths should be relative to the project root, so if you have a subdirectory app1/tests, then testpaths = tests won't work. Do a configuration per-app and place one pytest.ini with testpaths = tests in each of your app directories. – Anselma

In my project pytest successfully find tests when a path of the app1/tests is not specified. If I set testpaths = tests, pytest catch all tests in ./*/tests/test_*.py subdirectories. – Chenoweth

Answer 1

For example, you should put pytest.ini in the root directly of django-project as shown below:

django-project
 |-core
 |  └-settings.py
 |-my_app1
 |-my_app2
 |-pytest.ini # Here
 └-tests
    |-__init__.py
    └-test_1.py

In addition, if the specified testpaths below doesn't exist, the tests in tests folder are run:

# "pytest.ini"

[pytest]
DJANGO_SETTINGS_MODULE = core.settings
testpaths = my_tests # Doesn't exist
