如何使用junit 5春季引导编写pact-jvm消费者驱动程序pact测试？

Question

我是写契约测试用例的新手。我有一个非常简单的场景，一个微服务运行在dev服务器上，它基于路径变量(它是GET调用)返回true或false。如何编写生成协议的测试用例？如何为获得发布的契约设置代理服务器？目前，我只关心消费者的利益。

首先，我编写了以下代码？

OrderMsConsumerTest

@ExtendWith(PactConsumerTestExt.class)
@PactTestFor(providerName = "orderms-provider", port = "8888")
public class OrderMsConsumerTest {

    private static final String USER_SUBSCRIPTION_URL = "/api/order/order/subscription?userId=1&userSubscriptionId=1";
    private static final String SERVER_URL = "ACTUAL_SERVER_ADDRESS";

    @BeforeEach
    public void setUp(MockServer mockServer) {
        Assertions.assertTrue(mockServer != null);
    }

    @Pact(state = "user order subscription" , provider = "orderms-provider", consumer="orderms-consumer")
    public RequestResponsePact createPact(PactDslWithProvider builder) {
        Map headers = new HashMap<>();
        headers.put("Content-Type", "application/json;charset=UTF-8");
        return builder
                .given("Order User Subscription")
                .uponReceiving("user id and subscription id")
                .path("/api/order/order/subscription?userId=2968&userSubscriptionId=51230")
                .method("GET")
                .willRespondWith()
                .status(200)
                .headers(headers)
                .body("true")
                .toPact();
    }

    @Test
    @PactTestFor(pactMethod = "orderUserSubscription")
    void shouldPassResponseRecivedForGivenUserIdAndSubscriptionId() throws IOException {
        HttpResponse httpResponse = Request.Get(SERVER_URL + USER_SUBSCRIPTION_URL)
                .execute().returnResponse();
        Assertions.assertTrue(httpResponse.getStatusLine().getStatusCode() == 200);
    }
}

当我用intellij编写单击并运行测试时，结果会得到以下异常？

java.lang.UnsupportedOperationException: No method annotated with @Pact was found on test class OrderMsConsumerTest for provider 'orderms-provider'

我在这里有点困惑：@PactTestFor(providerName = " orderms-provider "，port =“8888”)--我目前还没有建立代理程序，所以它会自动运行一个在端口8888上具有提供者名称orderms- provider的模拟服务器？我是否需要在端口8888上运行一个应用程序并进行实际调用并通过测试？如何使测试用例作为maven构建的一部分运行？
