Running Python Tests

The project uses pytest to run Python tests and tox as a tool for running tests in different environments.

Setup Local development system

Using Python 3.6+, install the dev requirements:

pip install -r requirements-dev.txt

Run Python tests

Important: We recommend using tox for running tests locally. Please deactivate any conda environments before running tests using tox. Failure to do so may corrupt your virtual environments.

To run tests for a particular Python version (3.6 or 3.7):

tox -e py36  # or py37

This will run the tests and display coverage information.

Run linters

tox -e flake8
tox -e black

Run type checking

tox -e mypy

Run All Tests and Checks

tox
