Tests on Prefect flows and utilities

To run these tests, from the root directory of the repository:

• install development packages pip install -r requirements-dev.txt
• run pytest python -m pytest

Note that the pytest executable may or may not be based in your expected python environment, and using python -m pytest ensure that your local python environment is being used to run pytest.

To run pytest with logging pass-through, use

• python -m pytest -o log_cli=true -o log_level=info

By default tests that interact with external services like the VAN API or Redshift are skipped. Excluding these simplifies the test environment as you do not require credentials or internet access. The remaining tests run very quickly once the test environment is loaded. The tests in tests/tests_strive_ea.py in particular are very slow. Include all tests with:

• INCLUDE_EXTERNAL_TESTS=1 python -m pytest

Some other useful pytest command line options include:

• pytest --pdb will open a debugger if a test fails so you can inspect and interact with the stack
• pytest path/to/file/or/directory will run the tests just from that file or directory

pytest has many useful features and the pytest documentation is excellent.
