How to test @RestController when all of the mapping return with ResponseEntity?

I need to do unit testing on a @RestController where every method returns with a ResponseEntity. I have a CRUD repository to use but I don't know how can I test it with the ResponseEntities.

@RestController
@RequestMapping("/events")
public class EventController {
    @Autowired
    private EventRepository eventRepository;

    @GetMapping("")
    public ResponseEntity<Iterable<Event>> getAll() {
        return ResponseEntity.ok(eventRepository.findAll());
    }

    @GetMapping("/{id}")
    public ResponseEntity<Event> get(@PathVariable Integer id) {
        Optional<Event> event= eventRepository.findById(id);
        if (event.isPresent()) {
            return ResponseEntity.ok(event.get());
        } else {
            return ResponseEntity.notFound().build();
        }
    }

    @PostMapping("")
    public ResponseEntity<Event> post(@RequestBody Event event) {
        EventsavedEvent = eventRepository.save(event);
        return ResponseEntity.ok(savedEvent);
    }
.
.

So far so good , I can help you .

First of all, you must add unit test dependency. After that you must examine below code. Below code only consist for create. Good luck.

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.DEFINED_PORT)
@ActiveProfiles("dev")
public class EventControllerTests {

    @Autowired
    private TestRestTemplate testRestTemplate;

        @Test
        public void testCreateEvent() {
            Event event = new Event(); // Your entity
            event.setEventName("Test"); // Your entity attributes

            URI location = testRestTemplate.postForLocation("http://localhost:8080/events", event);

            Event event2 = testRestTemplate.getForObject(location, Event.class);

            MatcherAssert.assertThat(event2.getEventName(), Matchers.equalTo(event.getEventName()));


        }

}
