未检测到契约测试PactProviderRule

Question

我开始进行Pact测试，然后按照Pact-JVM-Example中的示例进行操作，然后创建了自己的测试

生产者从用户那里返回数据（非常简单的JSON）{“ id”：1“ firstName”：“名称”，“ lastName”：“姓氏”}

消费者测试是：

  public class HelloControllerTest {
  @Rule
  public PactProviderRuleMk2 provider = new PactProviderRuleMk2("DemoService", "localhost", 8112, this);

  @Pact(consumer = "DemoClient")
  public RequestResponsePact createFragment(PactDslWithProvider builder) {
    Map<String, String> headers = new HashMap();
    headers.put("Content-Type", "application/json");

    DslPart userResult = new PactDslJsonBody()
        .integerType("id",1)
        .stringType("fistName","name")
        .stringType("lastName","last")
        .asBody();

    return builder
        .given("There is a user with Id 1")
        .uponReceiving("A request for user 1")
        .path("/user/1")
        .method("GET")
        .willRespondWith()
        .status(200)
        .headers(headers)
        .body(userResult).toPact();
  }

  @Test
  @PactVerification()
  public void doTest() {
    HelloController helloController = new HelloController(provider.getPort());
  }
}

并且Consumer类看起来像：

public class HelloController {

  int port = 8200;

   HelloController(){
    // Will use default port.
    System.out.println("Default port "+ port);
  }

  HelloController(int port){
    this.port = port;
    System.out.println("Custom port "+ port);
  }

  public boolean getUser(){

    try {
    String url=String.format("http://localhost:%d/user/%d", port, 1);
    System.out.println("using url: " + url);
    HttpResponse r = Request.Get(url).execute().returnResponse();
    String json = EntityUtils.toString(r.getEntity());
    System.out.println("json = " + json);
    return true;
    }
    catch (Exception e) {
      System.out.println("Unable to get user");
      return false;
    }

  }

}

我注意到当我运行@Test时：

 @Test
  @PactVerification()
  public void doTest() {
    HelloController helloController = new HelloController(provider.getPort());
  }

我收到了NullPointerException。

测试未从@Rule中声明的提供程序获取模拟数据

@Rule
  public PactProviderRuleMk2 provider = new PactProviderRuleMk2("DemoService", "localhost", 8112, this);

我不知道缺少什么，为什么不检测Mock提供程序？

任何建议，谢谢

您必须在测试方法上注明您的契约片段。

@PactVerification(fragment = "createFragment")
