Testing

Testing is crucial for us and we strive for high coverage of our code.

We encourage you to write tests for every functionality you build and also update the existing ones if they need to.

pip install -r requirements.txt

Execute all tests with:

To run the tests we need to run this script

pytest

After finishing a task

Before pushing your changes, make sure you run the linter and prettier to ensure the code follows the rules, or the CI pipeline will throw an error and fail:
