我有这个方法：

@Transactional
@Service("vacancyService")
public class VacancyService {

   public boolean delete(Integer id) {
        Vacancy vacancy = vacancyDao.findById(id);
        return vacancy != null && vacancyDao.remove(vacancy);
    }
  ...
}

我想测试上述方法。

实现 vacancyDao.remove(vacancy)：

  public boolean remove(Vacancy vacancy) throws HibernateException {
            Session session = sessionFactory.getCurrentSession();
            if (vacancy == null) {
                return false;
            }

            int result = session.createQuery("delete from Vacancy where id = :id")
                    .setInteger("id", vacancy.getId()).executeUpdate();
            return result > 0;

        }

我的测试课：

@TransactionConfiguration(defaultRollback = false)
@ContextConfiguration(locations = { "classpath:/test/BeanConfig.xml" })
public class VacancyServiceTest extends AbstractTransactionalJUnit4SpringContextTests{

    @Test
    public void testDeleteMethod(){
        //what I can write here?
    }

我不知道如何测试这种方法。你能帮助我吗？

由于提供了服务类单元测试，这里是单元测试你的 Dao 类删除方法的方法

public class vacancyDaoTest {

@InjectMocks
VacancyDao vacancyDao = new VacancyDao();

@Mock
Session session;

@Mock
Query query;

@Mock
SessionFactory sessionFactory;

@BeforeClass
public void setup(){
    MockitoAnnotations.initMocks(this);
    when(sessionFactory.getSession()).thenReturn(session);
}



@Test
public void testRemove(){
    String hql = "delete from Vacancy where id = :id";
    when(session.createQuery(hql)).thenReturn(query);
    when(query.setInteger(eq("id"), anyInt())).thenReturn(query);
    when(query.executeUpdate).thenReturn(1);
    int result = vacancyDao.remove(new Vacancy());
    verify(session).createQuery(any(String.class));
    verify(query).setInteger(eq("id"), anyInt());
    verify(query).executeUpdate();
    assertNotNull(result);
    assertTure(result);


}

为了使其成为单元测试而不是集成测试，我将完全删除 spring 测试注释并通过像Mockito这样的模拟对象框架“注入”模拟服务。然后你需要几个简单的单元测试来覆盖几个条件。我会保存 DAO 层的集成测试。

作为第一个剪辑（省略了 Mockito 静态导入）：

@RunWith(MockitoJUnit4Runner.class)
public class VacancyServiceTest extends AbstractTransactionalJUnit4SpringContextTests{

    @InjectMocks private VacancyService vacancyService;
    @Mock private VacancyDAO vacancyDao;

    @Mock Vacancy vacancy;

    @Test
    public void testDeleteMethod_notFound(){
        when(vacancyDao.findById(10).thenReturn(null);

        assertFalse(vacancyService.delete(10));
    }

    @Test
    public void testDeleteMethod_foundButRemoveFailed(){
        when(vacancyDao.findById(10).thenReturn(mock(Vacancy.class));
        when(vacancyDao.remove(vacancy).thenReturn(false);

        assertFalse(vacancyService.delete(10));
    }

    @Test
    public void testDeleteMethod_success(){
        when(vacancyDao.findById(10).thenReturn(mock(Vacancy.class));
        when(vacancyDao.remove(vacancy).thenReturn(true);

        assertTrue(vacancyService.delete(10));
    }

您可以创建 Vacancy 对象，通过 Id 查询它，它应该返回值。然后删除它，然后查询id，如果id不存在你的测试应该通过。

但这不会是纯粹的单元测试，因为它假设“创建”和“按 id 查询”工作正常，如果它们有错误，这个测试也会失败，

您可以在 JUnit 中使用 Assume Tag，以确保此测试独立于通过 id 创建和查询。

另一个选项是使用带有 DBUnit 的 unitils，检查：http ://www.unitils.org/tutorial-database.html

编写您的测试类，如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:BeanConfig.xml",
        "classpath:data.xml" })
// This annotation is needed because the configuration does not support creation
// of non-transactional session.
@Transactional
public class VacancyServiceTest {

    @Autowired
    VacancyService serviceUnderTest;

    @Test
    public void test() {
        assertTrue(serviceUnderTest.delete(1));
    }

}

默认情况下，框架将为每个测试创建和回滚事务。即使测试方法在为测试管理的事务中运行时删除了选定表的内容，事务也会默认回滚，并且数据库将返回到执行测试之前的状态。
