And for this, we'll be using Spring's MockMvc. The controller layer is where our application interfaces with the outside world. The controller handles HTTP requests and returns responses. We'll be creating restful endpoints for a task management API. To test the controller layer, we'll use MockMvc. MockMvc is a powerful tool provided by Spring for testing Mvc applications. As the name predicts, there's simulation going on again. MockMvc allows us to simulate HTTP request and assert responses without actually starting a web server. This means our tests are focused on the controller's behavior and they're also, as a bonus, extra fast. I have a question for you.
