Spring MVC test

I am trying to learn spring, and I cannot find enough resources for testing, sorry for my English:) I have a controller class which returns ResponseEntity 

    @RestController
    @RequestMapping("/")
    public class OrderController {

    @Autowired
    private OrderRepository rep;

    @GetMapping("/{id}")
    public ResponseEntity<?> getOrderById(@PathVariable("id") String id){
        Order or = rep.findById(id).get();
        return ResponseEntity.ok(or); }
    @PostMapping("/add")
    public ResponseEntity<?> addOrder(@RequestBody Order order){
        rep.save(order);
        return ResponseEntity.ok(order);
}

I am trying to test with 

 @RunWith(SpringRunner.class)
 @WebMvcTest(OrderController.class)
 public class OrderControllerTest {

    @Autowired
    private MockMvc mockMvc;
    @MockBean
    private OrderRepository orderRepository;
    @Test
    public void shouldPresistOrder() throws Exception {

        this.mockMvc.perform(get("/ORD00001").accept("application/json"))
        .andExpect(status().isOk());}}

I get status expected<200> but was<404> Do I need to create an Order instance first, because it is a quite large class with lots of variables ? What are the ways of testing endpoints? Are there any books or online resources just for MVC testing purposes? Many thanks

You are mocking the OrderRepository class but there are no rules associated with it, create a dummy Order and Add the rule like this when(orderRepository.findById(<id in the dummy order>)).thenReturn(DummyOrder) In this way, you are setting the rules for OrderRepository to behave according to your needs.
