Mockito

when...thenXXX(not void) ... invoke when...thenAnswer ... ... invoke

doXXX...when (void)... invoke doAnswer...when(void)... invoke

BDDMockito

BDDMockito

given...willReturn

verify

Argument matchers ArgumentCaptor

@Mock @Spy @Captor @InjectMocks

SpringBoot: @MockBean @SpyBean

@Mock和@MockBean区别是什么？ @Mock和@InjectMocks区别是什么？ doAnswer.when和when thenReturn和when thenAnswer和doReturn when区别区别？ doAnswer.when返回空，就是void方法。

组合： @Mock和@InjectMock @MockBean和@Autowired

Use doAnswer() when you want to stub a void method with generic Answer.
