Spring Data Rest testing

Question

I'm developing the application by using Spring Data Rest. As you know, after creating simple repository interfaces, rest-endpoints are created by library.

Do I need to test these endpoints by integration tests? If yes, please provide any examples

Answer 1

here is the code snippet. read the full tutorial here

@Entity
@Table(name = "person")
public class Employee {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Size(min = 3, max = 20)
    private String name;

    // standard getters and setters, constructors
}

@Repository
public interface EmployeeRepository extends JpaRepository<Employee, Long> {
    public Employee findByName(String name);
}


@RunWith(SpringRunner.class)
@SpringBootTest(
  SpringBootTest.WebEnvironment.MOCK,
  classes = Application.class)
@AutoConfigureMockMvc
@TestPropertySource(
  locations = "classpath:application-integrationtest.properties")
public class EmployeeRestControllerIntegrationTest {

    @Autowired
    private MockMvc mvc;

    @Autowired
    private EmployeeRepository repository;

    @Test
public void givenEmployees_whenGetEmployees_thenStatus200()
  throws Exception {

    createTestEmployee("bob");

    mvc.perform(get("/api/employees")
      .contentType(MediaType.APPLICATION_JSON))
      .andExpect(status().isOk())
      .andExpect(content()
      .contentTypeCompatibleWith(MediaType.APPLICATION_JSON))
      .andExpect(jsonPath("$[0].name", is("bob")));
}
}

Aside from regular testing you can do with Spring (using MockMvc, RestAssured, RestTemplate etc), Traverson is a great API for specifically testing Spring HATEOAS. You can use it to test the validity of the links you are returning to your clients, see this example
