session - JUnit4 和 Mockito 进行单元测试

Question

public class DgiQtyAction extends DispatchAction {
    private final Logger mLog = Logger.getLogger(this.getClass());

    public ActionForward fnDgiQty(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)

            errorMessage.add(Globals.MESSAGE_KEY, new ActionMessage(EcoConstants.error_message,EcoConstants.SESSION_TIMEOUT));
            saveMessages(request, errorMessage); 
            request.setAttribute(EcoConstants.errorMessageType,EcoConstants.errorMessageType);
            return mapping.findForward(EcoConstants.SESSION_FORWARD);
        }
        String ecoPidID = (String) request.getParameter(EcoConstants.ecopidid);
        String pidId = ESAPI.encoder().encodeForHTML((String) request.getParameter(EcoConstants.pidid));

        mLog.debug("pidid  --------" + pidId);

public class DgiQtyActionTest {
    ActionMapping am;
    ActionForm af;
    DgiQtyAction dat;
    private MockHttpSession mocksession;

        mockresponse = new MockHttpServletResponse();
        ((MockHttpServletRequest) mockrequest).setSession(mocksession);
        mocksession.setAttribute("userBean","userBean");
         RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(mockrequest));
         mockrequest.addParameter("ecopid","something");
         mockrequest.addParameter("pid","<script>");
         Encoder instance = ESAPI.encoder();
         assertEquals("something",mockrequest.getParameter("ecopid"));
         assertEquals("&lt;script&gt;",instance.encodeForHTML(mockrequest.getParameter("pid")));
         dat=mock(DgiQtyAction.class);
         am=mock(ActionMapping.class);
         af=mock(ActionForm.class);
         dat.fnDgiQty(am,af,mockrequest,  mockresponse);
    }
}

我为上述课程编写了单元测试用例。我通过 jenkins 运行此代码并使用 sonarqube 作为代码覆盖率。我需要覆盖参数的 ESAPI 编码器，它构建成功但覆盖率没有增加。我找不到它的错误。请帮帮我。提前致谢
