Setting Up Unit Tests

Unit tests

The model tests are omitted here because they are essentially the same as in the impure section. In contrast to the tests on the impure service, we will now write unit tests for our routes.

This means that we will be able to test our routing logic without spinning up a database.

Test repository

To be able to test our routes, we will have to implement a TestRepository first, which we will use instead of the concrete implementation that is wired to a database.
