python manage.py test
This will execute all integration & unit tests and verify operation of the project.
A number of integration tests have been created which:
- test a variety of both valid and invalid lists.
- verify that failing to include the correct dict key gives an error.
- verify GET responds with an appropriate error.
- verify that failing to send a list gives an error.
These tests are not exhaustive, and more thought needs to be placed on edge cases.
The clean_number_list function was created and is being unit tested.
- verify that "good" lists are correctly cleaned.
- verify that "bad" lists return False.
