Currently struggling with problem when I get ‘mapping error for request’ with following controller/test configuration. Controller:
@Slf4j
@Validated
@RestController
@RequiredArgsConstructor
public class AdtechController {
private final AdtechService adtechService;
@PostMapping(value = "/subscriber/session")
public ResponseEntity<ResponseDto> submitSession(@RequestBody RequestDto requestDto) {
log.trace("execute submitSession with {}", requestDto);
ResponseDtoresponse = adtechService.submitSession(requestDto);
return new ResponseEntity<>(response, HttpStatus.OK);
}
@ExceptionHandler(AdtechServiceException.class)
public ResponseEntity<AdtechErrorResponse> handleAdtechServiceException(AdtechServiceException e) {
return new ResponseEntity<>(new AdtechErrorResponse(HttpStatus.INTERNAL_SERVER_ERROR.value(), e.getMessage()), HttpStatus.INTERNAL_SERVER_ERROR);
}
}
Test:
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@SpringJUnitConfig({AdtechTestConfig.class})
public class AdtechControllerTest {
private static final ObjectMapper OBJECT_MAPPER = JsonUtil.getJackson();
@Autowired
private MockMvc mockMvc;
@Test
public void testSubmitSession() throws Exception {
RequestDto requestDto = new RequestDto ();
requestDto.setKyivstarId("1123134");
requestDto.setMsisdn("123476345242");
requestDto.setPartnerId("112432523");
requestDto.setPartnerName("125798756");
String request = OBJECT_MAPPER.writeValueAsString(requestDto);
System.out.println("REQUEST: " + request);
String response = OBJECT_MAPPER.writeValueAsString(new ResponseDto("123"));
System.out.println("RESPONSE: " + response);
mockMvc.perform(post("/subscriber/session")
.content(MediaType.APPLICATION_JSON_VALUE)
.content(request))
.andDo(print())
.andExpect(status().isOk())
.andExpect(content().string(containsString(response)));
}
}
Configuration:
@Configuration
public class AdtechTestConfig {
@Bean
public AdtechService adtechTestService() {
return requestDto -> new AdtechResponseDto("123");
}
}
After test execution I get No mapping for POST /subscriber/session
The reason for the struggle is that my code from other modules with the same configuration works fine. Can somebody point out what am I missing ? Thanks in advance!

Apparently you are loading a configuration class to mock beans, this interferes with the other parts of Spring Boot and probably leads to partially loading your application. I suspect only the mocked service is available.
Instead of the test configuration use @MockBean to create a mock for the service and register behaviour on it.
@SpringBootTest
@AutoConfigureMockMvc
public class AdtechControllerTest {
private static final ObjectMapper OBJECT_MAPPER = JsonUtil.getJackson();
@Autowired
private MockMvc mockMvc;
@MockBean
private AdtechService mockService;
@BeforeEach
public void setUp() {
when(mockService.yourMethod(any()).thenReturn(new AdtechResponseDto("123"));
}
@Test
public void testSubmitSession() throws Exception {
// Your original test method
}
}
If the only thing you want to test is your controller you might also want to consider using @WebMvcTest instead of @SpringBootTest.
@WebMvcTest(AdTechController.class)
public class AdtechControllerTest {
private static final ObjectMapper OBJECT_MAPPER = JsonUtil.getJackson();
@Autowired
private MockMvc mockMvc;
@MockBean
private AdtechService mockService;
@BeforeEach
public void setUp() {
when(mockService.yourMethod(any()).thenReturn(new AdtechResponseDto("123"));
}
@Test
public void testSubmitSession() throws Exception {
// Your original test method
}
}
This will load a scaled-down version of the context (only the web parts) and will be quicker to run.
