java - 如何知道 HttpServletResponse 重定向到哪里？

Question

我正在学习软件测试，因为我主修计算机科学。教授给了我们一个用Java编写的程序的源代码来测试它。我现在正在测试这个方法:

    public static void createPanel(HttpServletRequest req, HttpServletResponse res, HttpSession hs) throws IOException
{
    String panelName = req.getParameter("panelName");
    String panelDescription = req.getParameter("panelDescription");
    int employeeID = ((EmployeeProfile)hs.getAttribute("User Profile")).EmployeeID;
    boolean result;

    //Let's validate our fields
    if(panelName.equals("") || panelDescription.equals(""))
        result =  false;
    else
        result = DBManager.createPanel(panelName, panelDescription, employeeID);
    b = result;

    //We'll now display a message indicating the success of the operation to the user
    if(result)
        res.sendRedirect("messagePage?messageCode=Panel has been successfully created.");
    else
        res.sendRedirect("errorPage?errorCode=There was an error creating the panel. Please try again.");

}

我使用 Eclipse 与 JUnit 和mockito 来测试所有方法，包括这个方法。对于这一特定方法，我想检查程序是否重定向到一个位置或另一个位置，但我不知道该怎么做。你有什么主意吗？谢谢。

实际上，您可以使用 Mockito 和 ArgumentCaptor 轻松实现它:

@RunWith(MockitoJUnitRunner.class)
public class MyTest {

   @Mock
   private HttpServletResponse response

   ...

   @Test
   public void testCreatePanelRedirection(){
      ArgumentCaptor<String> captor = ArgumentCaptor.forClass(String.class);
      YourClass.createPanel(request, response, session);
      verify(response).sendRedirect(captor.capture());
      assertEquals("ExpectedURL", captor.getValue());
   }
}
