问题描述

I’am trying to do a simple Integration test using Spring Boot Test in order to test the e2e use case. My test does not work because I’am not able to make the repository saving data, I think I have a problem with spring contexts …

JPA+Springboot 为某个service或者dao做单元测试时，发现始终插入不了数据。

测试代码如下：

@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);
    }
}

The test does not work, because the service is not saving the Person entity ….

问题解决

For each @Test function that makes a DB transaction, if you want to permanently persist the changes, then you can use @Rollback(false)
感觉@Test方法默认忽略掉了插入或者更新数据，如果你想在@Test方法内插入数据，需要加上@Rollback(false)注解。

@Rollback(false)
@Test
public void createPerson() throws Exception {
    int databaseSizeBeforeCreate = personRepository.findAll().size();

    // Create the Person
    restPersonMockMvc.perform(post("/api/people")
        .contentType(TestUtil.APPLICATION_JSON_UTF8)
        .content(TestUtil.convertObjectToJsonBytes(person)))
        .andExpect(status().isCreated());

    // Validate the Person in the database
    List<Person> personList = personRepository.findAll();
    assertThat(personList).hasSize(databaseSizeBeforeCreate + 1);
    Person testPerson = personList.get(personList.size() - 1);
    assertThat(testPerson.getFirstName()).isEqualTo(DEFAULT_FIRST_NAME);
    assertThat(testPerson.getLastName()).isEqualTo(DEFAULT_LAST_NAME);
    assertThat(testPerson.getAge()).isEqualTo(DEFAULT_AGE);
    assertThat(testPerson.getCity()).isEqualTo(DEFAULT_CITY);
}

I tested it with a SpringBoot project generated by jHipster:

  • SpringBoot: 1.5.4
  • jUnit 4.12
  • Spring 4.3.9
