Spring Boot - Unit Test on Controller - 404 Answer - spring-boot

Question

I am setting up the unit testing on my #RestController's, but It is not working correctly.
This is only a unit test to validate the answer from the method of the RestEndpoint, but It is not working, please help me because I tried a lot of configurations and read the documentation and nothing worked.
This is my endpoint:
#RestController
#RequestMapping("/clients")
public class ClientsEndpoint extends RestConfiguration {
#Autowired
private IClientService clientService;
#GetMapping(value = "/{id}")
private Object getById(#PathVariable(required = true) Long id) {
try {
Optional<Client> clientOptional = clientService.getById(id);
if (clientOptional.isPresent()) {
return clientOptional.get();
} else
return new GeneralResponse(ErrorsEnum.CLIENT_NOT_FOUND);
} catch (Exception e) {
log.log(Level.SEVERE, "Problemas al obtener datos del cliente con id: " + id, e);
return new GeneralResponse(ErrorsEnum.GENERAL_ERROR);
}
}
This is my Unit Test where I only added the mock of the endpoint and a simple call is done:
#RunWith(SpringRunner.class)
#WebMvcTest(ClientsEndpoint.class)
#ContextConfiguration(classes={ApplicationConfiguration.class})
public class QuarzoApiApplicationTests {
#Autowired
private MockMvc mockMvc;
#MockBean
private IClientService clientService;
#Test
public void getById() throws Exception {
Client client = new Client("Test", "Test", "Test", (byte) 1,
"Test", "Test", "Test", "Test", (byte) 1,
(byte) 1, (short)1, "Test" );
Optional<Client> clientOptional = Optional.of(client);
BDDMockito.given(clientService.getById(anyLong())).willReturn(clientOptional);
this.mockMvc.perform(get("/clients/1")
.header("Authorization","Bearer " + TestUtils.createToken("miltonc")))
.andExpect(status().isOk());
}
Results I am getting after running the unit test:

Answer 1

I finally solved this. I needed to include the #ComponentScan(basePackages = "io.quarzo.api.endpoints") to refer the endpoints I am trying to test.
My Test configuration:
#Configuration
#ComponentScan(basePackages = "io.quarzo.api.endpoints")
public class ApplicationConfiguration extends WebSecurityConfigurerAdapter {
After that, I had to Mock every bean I was using in the endpoints.
#MockBean(name = "clientRegistrationSingleton")
private Map<String, Client> clientsRegistering;
#MockBean
private IClientService clientService;
#MockBean
private IClientRepository clientRepository;
After that all was working ok, I can run the test and mock every Bean to test my #RestController's.
