如何将mock注入到具有@Transactional的@Service中

问题描述

我的单元测试中有任何问题，我有一些类似的东西。如果使用Transactional注释 blargh 函数，则会在someService上覆盖模拟注入。如果我删除了Transactional，那么模拟就会停留在那里。通过观察代码，当服务中的函数使用transactinal进行注释时，Spring似乎懒洋洋地加载服务，但是当服务中的函数没有进行注释时，它会急切地加载服务。这会覆盖我注入的模拟。

I have any issue in my unit test where I have something along the lines of this. The mock injection get overridden on the someService if the blargh function is annotated with Transactional. If I remove the Transactional the mock stays there. From watching the code it appears that Spring lazily loads the services when a function in the service is annotated with transactinal, but eagerly loads the services when it isn't. This overrides the mock I injected.

有更好的方法吗？

@Component
public class SomeTests
{
  @Autowired
  private SomeService someService;

  @Test
  @Transactional
  public void test(){
    FooBar fooBarMock = mock(FooBar.class);
    ReflectionTestUtils.setField(someService, "fooBar", fooBarMock);
  }
}

@Service
public class someService
{
  @Autowired FooBar foobar;

  @Transactional // <-- this causes the mocked item to be overridden
  public void blargh()
  {
    fooBar.doStuff();
  }
}

推荐答案

可能您可以尝试按以下方式实施测试：

Probably you could try to implement your test in the following way:

@Component
@RunWith(MockitoJUnitRunner.class)
public class SomeTests
{
  @Mock private FooBar foobar;
  @InjectMocks private final SomeService someService = new SomeService();


  @Test
  @Transactional
  public void test(){
    when(fooBar.doStuff()).then....;
    someService.blargh() .....
  }
}

我现在无法尝试，因为没有您的配置和相关代码。但这是测试服务逻辑的常用方法之一。

I could not try it right now as don't have your config and related code. But this is one of the common way to test the service logic.
