"""Tests for the application module.

How mocking works in this test suite:

1. The application_main() method is mocked using a side effect iterable. This allows us to pass a value in the first run, and then a KeyError in the second run to exit the loop.
2. All questions are mocked using return_value. This allows us to pass in a value to the question and then the method will return that value. This is useful for testing questionary prompts without user input.
