如何使用REST保证的从供应商向消费者注入Pact测试的动态ID

问题描述

我需要使用协议测试和REST保证检查类型为/ meeting / id的api。 ID可能会更改，我想在测试之前创建一个项目，然后注入其ID以覆盖合同url路径中设置的内容，但不确定如何执行此操作？

这是我的消费者：

@ExtendWith(PactConsumerTestExt.class)
public class PactConsumerTest {

Map<String,String> headers = new HashMap<>();


String storeMeetingPath = "/meeting/256";

@Pact(provider = VC,consumer = ED_UI)
public RequestResponsePact createPact(PactDslWithProvider builder) {

    headers.put("Content-Type","application/json");
    headers.put("Accept","application/json");

    return builder
            .given("A request to retrieve a meeting for a user")
            .uponReceiving("A request to retrieve a meeting for a user")
            .path(storeMeetingPath)
            .method("GET")
            .headers(headers)
            .willRespondWith()
            .body(new PactDslJsonBody()
                    .integerType("meetingId",3)
                    .stringType("meetingTitle","My title")
                    .stringType("meetingDescription","My description"))
            .status(200)
            .toPact();
}


@Test
@PactTestFor(providerName = VC,port = "8080")
public void runtest() {

    //Mock url
    RestAssured.baseURI = "http://localhost:8080";
    RequestSpecification rq = RestAssured
            .given()
            .headers(headers)
            .when();

    rq.get(storeMeetingPath);

}

}

这里是我的提供者：

@Provider(VC)
@PactFolder("target/pacts")
public class PactProviderTest {

@TestTemplate
@ExtendWith(PactVerificationInvocationContextProvider.class)
void pactTestTemplate(PactVerificationContext context,HttpRequest request) {
    request.addHeader("Authorization",AUTHORIZATION_TOKEN);
    context.verifyInteraction();
}

@BeforeEach
void before(PactVerificationContext context) {
    context.setTarget(new HttpsTestTarget(getBasePactEndpoint(),443,"/"));

    // Will create a meeting and retrieve the id from here but how to use this to overwrite what is there on the consumer?       

    getAuthorizationToken(UserType.TEACHER);
}

@State("A request to retrieve a meeting for a user")
public void sampleState() {

}

}

非常感谢您。

解决方法

了解了有关此问题的答案，以防对其他人有帮助：

替换此行

.path(storeMeetingPath)

使用

.pathFromProviderState("/meeting/${id}","/meeting/500")

这样我们就有一个带有默认值的模板。

然后改变

@State("A request to retrieve a meeting for a user")
public void sampleState() {

} 

要具有此属性，以便它返回一个映射，该映射将设置要注入的元素的键和值。

@State("A request to retrieve a meeting for a user")
public Map sampleState() {

    Map<String,Integer> map = new HashMap<>();
    map.put("id",391);

    return map;
}
