Testing the task manager

We’ve already covered the complete implementation of the task manager backend. In Chapter 2, Adding Persistence, we created the persistence layer for the application. Then, in Chapter 3, Creating the HTTP API, we implemented the business and presentation layers. Finally, in Chapter 4, Securing the Application, we secured the HTTP endpoints of the task manager. We could implement unit tests to verify the application functionality for each layer individually. However, this approach would require mocking each layer’s dependencies and would require a complex test implementation, which would also mean that its maintenance would be expensive. Since our business logic is not too complex, we’ll treat each of the individual application features as a test unit and implement an integration test for each functionality covering the three layers. Let us start by configuring our application.
