嘲笑注销会引发错误

Question

嗨，我有以下两个方法来登录，另一个被称为清除cookie。我首先嘲笑第二种删除cookie的方法。我从dzone转介了此代码。

我编辑了测试方法的代码。它运行良好，但我无法获得注销方法的解决方案

public class Service
{
    @RequestMapping(value = "/logout", method = RequestMethod.POST)
    public String logout(HttpServletRequest request,HttpServletResponse response) {
        HttpSession session = request.getSession(true);
    session.setAttribute("sessionid","id");
    Cookie first=new Cookie("name","Mycookie");
    response.addCookie(first);
        if (request.isRequestedSessionIdValid() && session != null) {
        session.invalidate();
        }
        HttpServletResponse sessionRes=handle(request,response);
    return "You have successfully logged out";
        }

    public HttpServletResponse handle(HttpServletRequest request, HttpServletResponse response)
    {
        Cookie[] cookies = request.getCookies();
        if(cookies!=null || cookies.length!=0)
        {
            for(Cookie cookie:cookies)
            {
                cookie.setMaxAge(0);
                cookie.setValue(null);
                cookie.setPath("/");
                response.addCookie(cookie);
            }
            response.addHeader("message", "No cookies found");
        }
        return response;
    }
}

处理注销工作正常，但无法进行测试记录方法，它使我抛出Null Pointer

@RunWith(MockitoJUnitRunner.class)
public class LogoutTest {
    @InjectMocks
    Service service;
    @Mock
    Cookie cookie;
    @Mock
    HttpServletRequest request;
    @Mock
    HttpServletResponse response;
    @Test
    public void TestHandle()
    {
        Cookie[] cookieArr = {cookie};
    response.addCookie(cookieArr[0]);
    when(request.getCookies()).thenReturn(cookieArr);
    service.handle(request, response);
   // verify(response).addCookie((Cookie) any());
    verify(response).addHeader("message", "No cookies found");
   Assert.assertEquals(cookie.getValue(),null);
    }
}

这是我注销的测试方法，它给我带来了奇怪的例外。我不知道我在哪里做错了。我也称为手柄方法。

@RunWith(MockitoJUnitRunner.class)
public class LogoutTest {
    @InjectMocks
    Service service;
    @Mock
    Cookie cookie=new Cookie("fname","ram");
    @Mock
    HttpServletRequest request;
    @Mock
    HttpServletResponse response;
    @Mock
    HttpSession session;
    @Test
    public void TestLogout()
    {
    session=request.getSession();
    request.setAttribute("sid", "id");
    Cookie[] cookieArr = {cookie};
    response.addCookie(cookieArr[0]);
    when(request.getCookies()).thenReturn(cookieArr);
    when(service.handle(request, response)).thenReturn(response);
     Assert.assertEquals("You have successfully logged out",service.logout(request, response));
    }
}

您使用

嘲笑错误

when(service.handle(request,response)).thenReturn(response);

意味着，嘲笑service，当从这种情况下调用handle方法时，返回response，因此您根本不测试handle方法。

@Test
public void test_handle() {
    Cookie[] cookieArr = {new Cookie("fname","ram")};
    when(request.getCookies()).thenReturn(cookieArr);
    service.handle(request, response);
    verify(response).addCookie(any());
    verify(response).addHeader("message", "No cookies found");
}
