How to write unit/integration test class for struts (1.2) Action class with Mockito

I have started to study how to write unit tests with Mockito version 1.9.5 .

And I need a help.

This is the code of my Action class which takes a request from a jsp page. In our project we use Struts 1.2 .

public class AdminViewSqlStatisticsAction extends AdminUserAction {

protected String findForward(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
        throws JspException, IllegalStateException {

    // First check everything was ok up the hierarchy
    String forward = super.findForward(mapping, form, request, response);

    if (null != forward) {
        return forward;
    }

    HttpSession session = request.getSession();
    ServletContext servletContext = (ServletContext) session.getServletContext();
    WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext);
    FantasyService fantasyService = (FantasyService) wac.getBean("fantasyService");
    Statistics statistics = fantasyService.getSessionFactory().getStatistics();
    Collection<OpenStatement> openStatements = SQLProfiler.getOpenStatements();

    Date created = FantasyService.created;
    Date cacheEmptied = FantasyService.cacheEmptied;
    long cacheEmptiedSeconds = (new java.util.Date().getTime() - FantasyService.cacheEmptied.getTime()) / 1000;
    Date currentDate = new Date();
    Collection<StoredObject> pageStatistics = ObjectStore.getStore("Page Profile").values();
    long pageStatisticsSeconds = (new Date().getTime() - ((LRUCache) ObjectStore.getStore("Page Profile")).getClearDate()
            .getTime()) / 1000;
    boolean isScoringRunning = fantasyService.isScoringRunning();
    String[] statisticsEntityName = statistics.getEntityNames();

    long max_memory = Runtime.getRuntime().maxMemory() / (1024 * 1024);
    long total_memory = Runtime.getRuntime().totalMemory() / (1024 * 1024);
    long free_memory = Runtime.getRuntime().freeMemory() / (1024 * 1024);
    long used_memory = total_memory - free_memory;
    long perc_used = (int) ((used_memory * 100) / max_memory);

    request.setAttribute("statistics", statistics);
    request.setAttribute("openStatements", openStatements);
    request.setAttribute("created", created);
    request.setAttribute("cacheEmptied", cacheEmptied);
    request.setAttribute("cacheEmptiedSeconds", cacheEmptiedSeconds);
    request.setAttribute("currentDate", currentDate);
    request.setAttribute("pageStatistics", pageStatistics);
    request.setAttribute("pageStatisticsSeconds", pageStatisticsSeconds);
    request.setAttribute("isScoringRunning", isScoringRunning);
    request.setAttribute("statisticsEntityName", statisticsEntityName);

    request.setAttribute("max_memory", max_memory);
    request.setAttribute("total_mamory", total_memory);
    request.setAttribute("free_memory", free_memory);
    request.setAttribute("used_memory", used_memory);
    request.setAttribute("perc_used", perc_used);

    String clearProfile = request.getParameter("clearProfile");
    if (clearProfile != null) {
        if (clearProfile.equals("all")) {
            ObjectStore.clear(null);
        } else {
            ObjectStore.clear(clearProfile + " Profile");
        }
    }
    return SessionLookup.FORWARD_SUCCESS_NO_INDEX_JSP;
}

protected Permission getPermission() {
    return null;
    }

}

I have started to write the unit/test class following the examples from internet and for the moment I have such code in my class.

@RunWith(MockitoJUnitRunner.class)
public class AdminViewSqlStatisticsActionTest {
@InjectMocks
private AdminViewSqlStatisticsAction adminViewSqlStatisticsAction = new AdminViewSqlStatisticsAction();

@Mock
private ActionMapping mapping;

@Mock
private AdminForm form;

@Mock
private HttpServletRequest request;

@Mock
private HttpServletResponse response;

@Test
public void testFindForwardSuccess() throws JspException {

    String result = adminViewSqlStatisticsAction.findForward(mapping, form, request, response);
    assertEquals(SessionLookup.FORWARD_SUCCESS_NO_INDEX_JSP, result);
    }
}

Is this code correct?

What code can I add to my test class?

Thank you for your help!
