我试图在我的服务上实施简单的单元测试。我的测试类的代码如下：
@RunWith(SpringRunner.class)
@SpringBootTest
public class UserServiceTest {
@Mock
private UserRepository userRepoMock;
private UserService userService;
private List<User> users;
@Before
public void setUp() throws Exception {
userService = new UserService(userRepoMock);
User u1 = new User();
u1.setEmail("test@test.com");
User u2 = new User();
u2.setEmail("test2@test.com");
users = Arrays.asList(u1, u2);
}
@Test
public void getAll() throws Exception {
when(userRepoMock.findAll()).thenReturn(users);
List<UserDTO> all = userService.getAll(new PageRequest(0, 20));
verify(userRepoMock).findAll();
}
}
执行测试时，我总是得到一个例外，这是摘录：
java.lang.IllegalStateException: Failed to load ApplicationContext
...

我的代码有什么问题？我应该包含一些未包含在spring-boot-starter-test中的依赖项吗？
注意我使用的是Spring Boot v 1.5.1和Spring Data MongoDB存储库。
