NullPointerException in verifyForward()

[Brandon Stewart]

All of our tests throw a NullPointerException when calling verifyForward after actionPerform():
There was 1 error:
1) testNotLoggedIn(test.com.galileo.fares.llpf.struts.TestEditUserAction)
java.lang.NullPointerException
    at servletunit.struts.MockStrutsTestCase.getActualForward(MockStrutsTestCase.java:418)
    at servletunit.struts.MockStrutsTestCase.verifyForward(MockStrutsTestCase.java:434)
    at test.com.galileo.fares.llpf.struts.TestEditUserAction.testNotLoggedIn(TestEditUserAction.java:40)
    at test.com.galileo.fares.llpf.struts.TestEditUserAction.main(TestEditUserAction.java:23)

The problem seems to be that the RequestDispatcher in the ServletContextSimulator has not been initialized.  Any suggestions?

Could you give more details, e.g. code, mapping, using Tiles or not?

After further research, the problem seems to occur only for actions defined with scope="session".

This test generates the error:
    public void testNotLoggedIn() {
        setRequestPathInfo("/editUser");
        actionPerform();      
        verifyForward("login");
        verifyNoActionErrors();
    }

This is the action mapping in struts-config:
      <action path="/editUser"               type="com.galileo.fares.llpf.struts.EditUserAction"
              name="editUserForm"
              scope="session"
              validate="false">
      </action>

You haven't defined "<forward>" in your "<action>" tag, e.g.

<forward name="Success" path="/details.jsp"/>
