So when you try to access the 'str' using classA object it causes null pointer exception as classA is yet to be autowired. Instead make POService porderService a field and annotate with @InjectMocks so it will automatically create an instance and assign the mocked objects to its field and constructor (or just injec both through the. All other bean wiring seems ok as the Spring boot application can start (when I comment out the test class). factory; 事前準備. 275. initMocks(this) 方法初始化这些mock并为每个测试方法注入它们，因此需要在 setUp() 方法中调用它。@InjectMocks 是一种 Mockito 机制，用于将 test 类中声明的字段注入(inject)到 under test 类中的匹配字段中。 它不要求被测类是 Spring 组件。 @Autowired 是 Spring 的注释，用于将 bean Autowiring 到生产、非测试类中。. Mock the jdbcTemplate 2) use @injectMocks. You can use the @SpringBootTest annotation. 使用Mock打桩的为MyRepository，原本以为使用InjectMocks后，MyService会自动. class) or use the MockitoAnnotations. In mockito-based junit tests, @Mock annotation creates mocks and @InjectMocks creates actual objects and injects mocked dependencies into it. Use @SpringBootTest or @SpringMvcTest to start a spring context together with @MockBean to create mock objects and @Autowired to get an instance of class you want to test, the mockbeans will be used for its autowired dependencies. If you don't use Spring, it is quite trivial to implement such a utility method. (@Autowired). SpringExtension is used with JUnit 5 Jupiter @ExtendWith annotation as following.
