弹簧开机测试@Transactional不保存

java spring spring-boot spring-test

我正在尝试使用Spring Boot Test进行简单的集成测试，以测试e2e用例。我的测试不起作用，因为我无法使存储库保存数据，我认为我对弹簧上下文有问题......

这是我的实体：

@Entity
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
public class Person {
    @Id
    private int id;
    private String name;
}

这是人员存储库：

@Repository
public interface PersonRepository extends JpaRepository<Person, Integer> {
}

专人服务：

@Service
public class PersonService {

    @Autowired
    private PersonRepository repository;

    public Person createPerson(int id,String name) {
       return repository.save(new Person(id, name));
    }

    public List<Person> getPersons() {
      return repository.findAll();
    }
}

人员控制器：

@RequestMapping
@RestController
public class PersonController {

  @Autowired
  private PersonService personService;

  @RequestMapping("/persons")
  public List<Person> getPersons() {
      return personService.getPersons();
  }

}

主要应用程序类：

@SpringBootApplication
public class BootIntegrationTestApplication {

  public static void main(String[] args) {
    SpringApplication.run(BootIntegrationTestApplication.class, args);
  }
}

应用程序属性文件：

spring.datasource.url= jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=create
spring.jpa.show-sql=true

和测试：

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class BootIntegrationTestApplicationTests {

    @Autowired
    private PersonService personService;
    @Autowired
    private TestRestTemplate restTemplate;

    @Test
    @Transactional
    public void contextLoads() {
        Person person = personService.createPerson(1, "person1");
        Assert.assertNotNull(person);

        ResponseEntity<Person[]> persons = restTemplate.getForEntity("/persons", Person[].class);
    }
}

测试不起作用，因为服务未保存 Person 实体....提前致谢

答案 1

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
public class SmokeTest {

    @Autowired
    UserController userController;

    @Autowired
    UserDao userDAO;

    @Rollback(false) // This is key to avoid rollback.
    @Test   
    public void contextLoads() throws Exception {
        System.out.println("Hiren");

        System.out.println("started");
        userDAO.save(new User("tyx", "x@x.com"));
    }
}

引用是避免回滚的关键。@Rollback(false)

答案 2

感谢M. Deinum，我想我明白了，所以最好的方法是将测试的逻辑分成两个测试，第一个测试将只测试服务（所以这个可能是事务性的），第二个是控制器：

测试 1：

@Test
@Transactional
public void testServiceSaveAndRead() {
    personService.createPerson(1, "person1");
    Assert.assertTrue(personService.getPersons().size() == 1);
}

测试 2：

@MockBean
private PersonService personService;

@Before
public void setUp() {
    //mock the service
    given(personService.getPersons())
            .willReturn(Collections.singletonList(new Person(1, "p1")));
}

@Test
public void testController() {
    ResponseEntity<Person[]> persons = restTemplate.getForEntity("/persons", Person[].class);
    Assert.assertTrue(persons.getBody()!=null && persons.getBody().length == 1);
}
