Spring Boot Web Test - 404 Not found - spring

Question

I am trying to test the Controller of a very simple GET request with #WebMvcTest but I'm getting 404 instead of 200 and the console does not give me anything useful to understand what is going on.
I've put a breakpoint at the beginning of the controller but it never arrives. If I run the application, the endpoint works as expected.
Here's my controller:
#RestController
public class RegistroClienteController {
#GetMapping("/api/registro-cliente")
public ResponseEntity<Void> crearCliente() {
return new ResponseEntity<Void>(HttpStatus.OK);
}
}
And here's my test:
#RunWith(SpringRunner.class)
#WebMvcTest(RegistroClienteController.class)
#ContextConfiguration(classes = { SecurityConfig.class })
public class RegistroClienteControllerTest {
#Autowired
private MockMvc mockMvc;
#MockBean
UserDetailsService userDetailsService;
#Test
public void test() throws Exception {
//#formatter:off
mockMvc
.perform(get("/api/registro-cliente"))
.andExpect(status().isOk());
//#formatter:on
}
}
And console's output:
MockHttpServletRequest:
HTTP Method = GET
Request URI = /api/registro-cliente
Parameters = {}

Answer 1

I was having the same error and after hours of searching found that the error is due to controller not being registered. The problem is described here.
Apparently, the following is not enough.
#WebMvcTest(controllers = {<ControllerToTest>.class})
You need to do,
#WebMvcTest(controllers = {<ControllerToTest>.class})
#Import(<ControllerToTest>.class)

Answer 2

I can try to change the annotations
#WebMvcTest(RegistroClienteController.class)
to
#SpringBootTest(classes = {your application class}.class)
