问题描述
我想模拟我的存储库中提供的查询,如下所示:
I want to mock a query provided on my repository like this:
@Test
public void GetByEmailSuccessful() {
// setup mocks
Mockito.when(this.personRepo.findAll()
.stream()
.filter(p -> (p.getEmail().equals(Mockito.any(String.class))))
.findFirst()
.get())
.thenReturn(this.personOut);
Mockito.when(this.communityUserRepo.findOne(this.communityUserId))
.thenReturn(this.communityUserOut);
...
我的 @Before
方法如下所示:
@Before
public void initializeMocks() throws Exception {
// prepare test data.
this.PrepareTestData();
// init mocked repos.
this.personRepo = Mockito.mock(IPersonRepository.class);
this.communityUserRepo = Mockito.mock(ICommunityUserRepository.class);
this.userProfileRepo = Mockito.mock(IUserProfileRepository.class);
}
遗憾的是,当我运行测试时收到错误:
Sadly when I run the test I receive the error:
何时我双击它指向第一个lambda的 .get()
方法的错误。
When I double-click the error it points at the .get()
method of the first lambda.
有任何错误你成功地模拟了一个lambda表达式并知道如何解决我的问题吗?
Have any of you successfully mocked a lambda expression and know how I can solve my problem?
推荐答案
没有必要模拟这样的深度调用。只需模拟 personRepo.findAll()
并让Streaming API正常工作:
There's no need to mock such deep calls. Simply mock personRepo.findAll()
and let the Streaming API work as normal:
Person person1 = ...
Person person2 = ...
Person person3 = ...
List<Person> people = Arrays.asList(person1, person2, ...);
when(personRepo.findAll()).thenReturn(people);
然后代替
.filter(p - >(p.getEmail()。equals(Mockito.any(String.class))))
在 Person
对象上设置/模拟电子邮件
作为预期值。
just set/mock email
on your Person
objects to be the expected value.
或者,考虑实施 PersonRepo.findByEmail
。
