jUnit assertEquals 문자열 반환 값 "50"은 "50"이지만 반환 값은 없습니다. 테스트

Question

jUnit 및 REST 웹 서비스를 실험합니다. 다음과 같은 클래스와 테스트 클래스를 작성하여 테스트했습니다. 테스트를 잘못 작성했거나 서비스가 잘못 작성되었습니다.

나는 그것이 return "50"; 또는
은 또한 50 경로를 복귀하도록되어한다고 생각? 그 테스트를 어떻게 작성합니까?

클래스 :

@Path("/QAService") 
public class QAService { 
    @GET() 
    //@Path("/") 
    @Produces("text/plain") 
    public String getServiceInfo() { 
     return "50"; 
    } 

클래스의 시험 :

public class QAServiceTest { 
    @Test 
    public void testgetServiceInfo() { 

     String expected = "50"; 

     //create static variable to call non-static variable. assertEquals. 
     QAService qas = new QAService(); 
     qas.getServiceInfo(); 
     assertEquals(expected, qas); 
    } 

그러나 가지고 테스트 결과 :

expected:<50> but was:<com.hey.BLA.zurich.QAService@52bb855b>

당신은 아마 의미 :

assertEquals(expected, qas.getServiceInfo());
