Mockito 的 R2dbc 存储库始终为空
R2dbc Repositories always null with Mockito
我正在尝试测试服务，但存储库始终为空。使用 JPA 存储库时，我从未遇到过这个问题。我不确定它是否与 ReactiveCrudRepository 有关。有人遇到过这个问题吗？
@RunWith(MockitoJUnitRunner.class)
class UserTest {
@InjectMocks
private UserService underTest;
@Mock
private UserRepository userRepository;
@Mock
private AutoCloseable closeable;
@BeforeEach
public void init() {
closeable = MockitoAnnotations.openMocks(this);
}
@AfterEach
public void closeService() throws Exception {
closeable.close();
}
@Test
void getApplicableUsers() {
when(userRepository.findAll().collectList().block()).thenReturn(new ArrayList<>());
Set<User> expected = underTest.getUsers(getUser(), getUsers());
verify(underTest, times(1)).updateUsers(getUser(),expected);
}
}

------------更新 1 ------
我想出了问题所在，但没有找到解决方案。如果我使用 .block 它总是空的，但是在这种情况下我需要使用块。有没有人能够使用 block 或 optionalBlock() 并能够模拟它？
findAll() 方法未被模拟，因此返回空值。你应该模拟 userRepository.findAll() 而不是 userRepository.findAll().collectList().block().
试试这个：
when(userRepository.findAll()).thenReturn(Flux.empty());
您能否验证您的服务 class 并查看您是否有任何构造函数但在构造函数中没有您的回购协议。您需要删除构造函数或使用以 null 形式出现的 repo 初始化您的服务对象。我今天有这个问题；我删除了构造函数并且它起作用了。
我正在尝试测试服务，但存储库始终为空。使用 JPA 存储库时，我从未遇到过这个问题。我不确定它是否与 ReactiveCrudRepository 有关。有人遇到过这个问题吗？
