Java @Mock jpaRepository调用real save方法，而@MockBean调用Mock方法

我认为我理解@Mock和@MockBean之间的区别，即使我认为任何被模拟的对象都不会调用真正的方法，尽管当我在测试下面运行时，我可以看到basket已经插入到hsqldb日志中。所以现在我对为什么在使用@Mock时插入basket而在使用@MockBean时不插入basket感到有点困惑

另一方面，如果我这样做，那么hsqldb是干净的。在这两种情况下，测试都是成功的

@MockBean
private BasketRepository basketRepo;

@MockBean是一个Spring注释，应该在集成测试中使用，以便用模拟的bean替换真实的bean：

可用于向弹簧添加模拟的注释 应用程序上下文

Mockitos@Mock创建该存储库的模拟，但不将其注入BasketService

如果确实需要使用Mockitos mocked版本，则必须在测试中手动执行：

@Mock
private BasketRepository basketRepo;

@Test
public void createBasketWithSameOrderRef() throws Exception
{
   basketService.setBasketRepository(basketRepo);
   ...

我写了一篇关于你是否需要进一步阅读的文章。

啊，我明白了！顺便说一句，我注释掉了前2个——关联到basketRepo——我得到了相同的结果，basket被插入。因此，平均测试使用@Autowired basketRepo而不是模拟的。谢谢
