Python Testing with pytest

Specifying Test Directory Locations

Whereas norecursedirs tells pytest where not to look, testpaths tells pytest where to look. testspaths is a list of directories relative to the root directory to look in for tests. It’s only used if a directory, file, or nodeid is not given as an argument.

Suppose for the Tasks project we put pytest.ini in the tasks_proj directory instead of under tests:

tasks_proj/
├── pytest.ini
├── src
│   └── tasks
│       ├── api.py
│       └── ...
└── tests
    ├── conftest.py
    ├── func
    │   ├── __init__.py
    │   ├── test_add.py
    │   ├── ...
    └── unit
        ├── __init__.py
        ├── test_task.py
        └── ...

It could then make sense to put tests in testpaths:

[pytest]
testpaths = tests

Now, as long as you start pytest from ...
