Spring Boot Test MockMvc perform post - Not working - spring

Question

I'm trying to make a Integration test using the Spring Boot but the post request is not working. The method saveClientePessoaFisica is never called and do not return any kind of error! I just tried to make other tests using a get method and it works properly.
#RunWith(SpringRunner.class)
#SpringBootTest
#AutoConfigureMockMvc
#ActiveProfiles("dev")
public class ClienteControllerIT {
#Autowired
private MockMvc mvc;
#Test
public void nao_deve_permitir_salvar_cliente_pf_com_nome_cpf_duplicado() throws Exception {
this.mvc.perform(post("/api/cliente/pessoafisica/post")
.contentType(MediaType.APPLICATION_JSON)
.content("teste")
.andExpect(status().is2xxSuccessful());
}
}
#RestController
#RequestMapping(path = "/api/cliente")
public class ClienteController {
#Autowired
private PessoaFisicaService pessoaFisicaService;
#PostMapping(path = "/pessoafisica/post", consumes = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Void> saveClientePessoaFisica(#RequestBody PessoaFisica pessoaFisica) throws Exception {
this.pessoaFisicaService.save(pessoaFisica);
return new ResponseEntity<Void>(HttpStatus.CREATED);
}
}

Answer 1

Your content "teste" is no valid JSON. When I am using your code, I'm getting a JsonParseException complaining about that (By the way, there is a parenthese missing after content("teste") ). Also helpful is using andDo(print()) which will give you the request and response in more detail:
#Test
public void nao_deve_permitir_salvar_cliente_pf_com_nome_cpf_duplicado() throws Exception {
this.mvc.perform(post("/api/cliente/pessoafisica/post")
.contentType(MediaType.APPLICATION_JSON)
.content("teste"))
.andDo(print())
.andExpect(status().is2xxSuccessful());
}

Some things to look for :
Enable logging in your mockmvc
Enable your mockmvc properly
When using spring security, initialise it in mockmvc
When using spring security / CSRF / HTTP POST , pass a csrf in your mockmvc
Enable debug logging
Like this :
logging:
level:
org.springframework.web: DEBUG
org.springframework.security: DEBUG
Working test :
#RunWith(SpringRunner.class)
#SpringBootTest
#ActiveProfiles("test")
#AutoConfigureMockMvc
public class MockMvcTest {
#Autowired
protected ObjectMapper objectMapper;
#Autowired
private MockMvc mockMvc;
#Autowired
private WebApplicationContext webApplicationContext;
#Before
public void init() throws Exception {
mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).apply(springSecurity()).build();
}
#Test
public void adminCanCreateOrganization() throws Exception {
this.mockMvc.perform(post("/organizations")
.with(user("admin1").roles("ADMIN"))
.with(csrf())
.contentType(APPLICATION_JSON)
.content(organizationPayload("org1"))
.accept(APPLICATION_JSON))
.andDo(print())
.andExpect(status().isCreated());
}
}
