//Another useful approach is to not start the server at all but to test only the layer below that, where Spring handles
// the incoming HTTP request and hands it off to your controller. That way, almost of the full stack is used,
// and your code will be called in exactly the same way as if it were processing a real HTTP request
// but without the cost of starting the server. To do that, use Spring’s MockMvc and ask for that to be injected for
// you by using the @AutoConfigureMockMvc annotation on the test case.
