Question

我编写了一个调用POST服务的程序

package itss;
import java.util.concurrent.CompletionStage;
import javax.inject.Inject;
import org.junit.Test;
import play.libs.Json;
import play.libs.ws.WSBodyReadables;
import play.libs.ws.WSBodyWritables;
import play.libs.ws.WSClient;
import play.libs.ws.WSResponse;
import com.fasterxml.jackson.databind.JsonNode;
public class IntegrationTest implements WSBodyReadables, WSBodyWritables {
     private final WSClient ws;
        @Inject
        public IntegrationTest(WSClient ws) {
            this.ws = ws;
        }

     @Test
     public void sendSmsMessage() {
         try
         {
            JsonNode json = Json.newObject().put("calledfrom", "dsddsds");
            String url = "http://xx.xxx.xxx.xxx:8081/FS/fsqa/cd";
            CompletionStage<WSResponse> responseCompletionStage = ws.url(url).setContentType("application/json").post(json);
            responseCompletionStage.handle((result, error) -> {
                try
                {
                 System.out.println("I am called");
                 System.out.println("Body results is "+result.getBody().toString());
                 System.out.println("into error"+error.getMessage());
                }
                catch(Exception e)
                {
                    e.printStackTrace();
                }
                return responseCompletionStage;

            });

         }
         catch(Exception e)
         {
             e.printStackTrace();

         }
        }
}

当我通过sbt console（test）运行上述程序时

它给了我以下异常

[info] Test itss.IntegrationTest.initializationError started

有人可以告诉我如何解决这个问题。

我正在使用play framewrk 2.6

这是我的build.sbt

version := "2.6.x"

Answer 1

JUnit不理解或不支持WSClient注释，因此使用它注释构造函数将无济于事。您必须在测试中实例化您自己的{{1}}，并在测试完成时将其拆除。 Play documentation on WSClient详细说明了如何执行此操作。

测试类应该只有一个公共构造函数
