microservices - Zuul 过滤器的 SpringBoot Junit 测试

Question

我是 Zuul J-unit 测试的新手。我有几个过滤器，它们是 ChangeRequestEntityFilter 和 SessionFilter，我在下面粘贴了我的过滤器代码。谁能告诉我如何为过滤器编写 Junit。我已经搜索并尝试使用 MockWire 进行单元测试(我还粘贴了带有基本注释和 WireMock 端口的空方法)。我至少需要一个适当的例子，说明 Zuul 的 J-unit 是如何工作的。我提到了 http://wiremock.org/docs/getting-started/医生。我知道该做什么，但不知道该怎么做。

public class ChangeRequestEntityFilter extends ZuulFilter {

    @Autowired
    private UtilityHelperBean utilityHelperBean;

    @Override
    public boolean shouldFilter() {
        // //avoid http GET request since it does'nt have any request body
        return utilityHelperBean.isValidContentBody();
    }

    @Override
    public int filterOrder() {
        //given priority
    }

    @Override
    public String filterType() {
        // Pre
    }

    @Override
    public Object run() {

        RequestContext context = getCurrentContext();

        try {
            /** get values profile details from session */
            Map<String, Object> profileMap = utilityHelperBean.getValuesFromSession(context,
                    CommonConstant.PROFILE.value());

            if (profileMap != null) {
                /** get new attributes need to add to the actual origin microservice request payload */
                Map<String, Object> profileAttributeMap = utilityHelperBean.getProfileForRequest(context, profileMap);
                /** add the new attributes in to the current request payload */
                context.setRequest(new CustomHttpServletRequestWrapper(context.getRequest(), profileAttributeMap));
            }

        } catch (Exception ex) {
            ReflectionUtils.rethrowRuntimeException(new IllegalStateException("ChangeRequestEntityFilter : ", ex));
        }

        return null;
    }

}

我知道，我要求更多。但是给我任何简单的工作完整示例，我都可以接受。

我当前的代码带有基本注释和 WireMock 端口。

@RunWith(SpringRunner.class)
@SpringBootTest
@DirtiesContext
@EnableZuulProxy
public class ChangeRequestEntityFilterTest {

    @Rule
    public WireMockRule wireMockRule = new WireMockRule(8080);

    @Mock
    ChangeRequestEntityFilter requestEntityFilter;

    int port = wireMockRule.port();

    @Test
    public void changeRequestTest() {

    }
}

你试过@MockBean了吗？

https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/test/mock/mockito/MockBean.html

“当@MockBean 在字段上使用时，以及在应用程序上下文中注册时，模拟也会被注入(inject)到字段中。典型用法可能是:”

@RunWith(SpringRunner.class)
public class ExampleTests {

     @MockBean
     private ExampleService service;

     @Autowired
     private UserOfService userOfService;

     @Test
     public void testUserOfService() {
         given(this.service.greet()).willReturn("Hello");
         String actual = this.userOfService.makeUse();
         assertEquals("Was: Hello", actual);
     }

     @Configuration
     @Import(UserOfService.class) // A @Component injected with ExampleService
     static class Config {
     }

}
