This is a 3 part series for unit testing the controller, service, and repository layers in a typical REST architecture.

Update the app module: Now we can start up the app and call the endpoint using Postman to call it: And we get a response of SpaceShip: We can also test the ID by sending an incorrect spaceShipId and see the expected response: This concludes the 3 part series for unit testing the API layers.
