Testing

We use pytest for testing. Please try to ensure that all functions are tested, including both unit and integration tests.

Long running tests

Some tests may take a long time, e.g. those requiring TensorFlow if you don’t have a GPU. These tests should be marked with @pytest.mark.slow, e.g.:

import pytest
@pytest.mark.slow
def test_something_slow() -> None:
    slow_result = run_slow_processes()
    assert slow_result == expected_slow_thing, "some useful error message"

During development, these “slow” tests can be skipped by running pytest -m "not slow".

Continuous integration

A GitHub actions workflow (.github/workflows/test_and_deploy.yml) has been set up to run (on each commit/PR):

• Linting checks (pre-commit).

• Testing (only if linting checks pass)

• Release to PyPI (only if a git tag is present and if tests pass). Requires TWINE_API_KEY from PyPI to be set in repository secrets.

Many of these workflows use actions from neuroinformatics-unit/actions. Feel free to raise a PR to that repository!
