我有以下测试类，旨在Service在我的MVC模型中为我的类运行 junit 测试。这是我的课ExpertsServiceTest.java：


@RunWith(SpringRunner.class)
@RequiredArgsConstructor
@Component
public class ExpertsServiceTest {


    @Autowired
    private  ExpertRepository repository;

    @Autowired
    private ExpertsServiceImpl service;


    Experts demoExpert = new Experts(ObjectId.get(),"Steve Jobs", "Enterpreneur",
            Availability.BUSY, Language.CHINESE);



    @Before
    public void setUp() throws Exception{
        service.deleteAll();
        service.createExpert(demoExpert);

    }

    @After
    public void tearDown() throws Exception{
        service.deleteAll();
    }

    @Test
    public void testFindAll(){
        List<Experts> expertEntries = service.findAll();
        assertEquals(2, expertEntries.size());
    }
}

但是，当我运行测试时，我遇到了以下错误：


org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'demo.ExpertsServiceTest': Unsatisfied dependency expressed through field 'repository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'demo.ExpertRepository' available: expected at least 1 bean which qualifies as autowire candidate.

您没有提供应用程序上下文信息

请使用@ContextConfiguration 注释测试类并提供配置类。如下

package com.example;

@RunWith(SpringJUnit4ClassRunner.class)
// ApplicationContext will be loaded from the OrderServiceConfig class
@ContextConfiguration(classes=OrderServiceConfig.class, loader=AnnotationConfigContextLoader.class)
public class OrderServiceTest {

    @Autowired
    private OrderService orderService;

    @Test
    public void testOrderService() {
        // test the orderService
    }
}

您没有 spring 上下文，您应该使用：'@SpringBootTest' 注释。你可以在这里阅读更多：SpringRunner vs SpringBootTest
