Question

当提供某些特定属性时，如何测试spring bean引发异常？

我尝试使用AutowireCapableBeanFactory，但是在运行任何测试方法之前都会抛出Bean实例化异常。

@RunWith(SpringRunner.class)
@SpringBootTest(
        properties = {
                // these properties will cause an exception in getMyService
        },
        classes = {MySpringBootApp.class}
)
public class TestBeanInitThrowsException {

    @Autowired
    private AutowireCapableBeanFactory beanFactory;

    @Test
    public void test1() {
        this.beanFactory.createBean(OtherServiceThatRequiresMyService.class);
    }

}

@Configuration
public class MyConf {
    @Value("${xyz}")
    private Resource xyz;

    @Bean public MyService getMyService(OtherBean bean) {
       // use xyz to create MyService
       // can throw exceptions
    }
}

您可以对配置类进行单元测试。

@RunWith(MockitoJunitRunner.class)
class ConfTest {
    @InjectMocks MyConf sut;
    @Mock Resource xyz;

    @Test(expected = InvalidParameterException.class)
    public void testInvalidResourceThrowsException() {
        when(xyz.mappedName()).thenReturn("invalid"); // or something
        OtherBean param = mock(OtherBean.class);

        sut.getMyService(param);
    }
}

测试该bean实例引发异常
