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);
}
...
}
我想测试上面的方法。
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;
}
我的测试班:
@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。你能救我吗?

由于提供了服务类单元测试,以下是对Dao类删除方法进行单元测试的方法
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);
}
}

为了使它成为单元测试而不是集成测试,我将完全删除弹簧测试注释并注入&#34;注入&#34;通过像Mockito这样的模拟对象框架的模拟服务。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));
}

你可以创建空缺对象, 通过Id查询,它应该返回值。 然后删除它, 然后查询id,如果id不存在,则测试应该通过。
但这不是纯单元测试,因为它假设“创建”和“按ID查询”工作正常,如果它们有错误,此测试也将失败,
您可以在JUnit中使用Assume Tag,以确保此测试独立于id的创建和查询。
另一个选项是使用带有DBUnit的单元,检查:http://www.unitils.org/tutorial-database.html

将测试类编写为:
@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并回滚事务。即使测试方法在为测试管理的事务中运行时删除了所选表的内容,该事务也将默认回滚,并且数据库将在执行测试之前返回其状态。
