spring-boot - 如何使用 junit 5 spring boot 编写 pact-jvm 消费者驱动程序协议测试？
问题描述
我是编写 PACT 测试用例的新手。我有一个非常简单的场景，一个微服务在开发服务器上运行，它根据路径变量（它的一个 GET 调用）返回 true 或 false。如何编写生成 PACT 的测试用例？如何为协议设置代理服务器以进行发布？目前我只关心消费者端。
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);
}
}
当我在 intellij 中编写 click 并运行测试时，我得到以下异常结果？
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")我现在没有设置代理，所以它会在端口 8888 自动运行一个提供者名称 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我的 Maven 构建的一部分运行？
解决方案
@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 orderUserSubscription(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);
}
}
