Testing with DropDowns - onChange event

[Verma Shalini (HCTM/ETA)]

I'm trying to test onChange even on one dropdown so that the value is changed 
in the other dropdown.When I submit the form I'm not able to get the values for 
any of the fields.
I have seen people getting the same error but there is no solution so far.
Thanks for helping in advance.


 @Test
    public void testDummyPage() throws Exception
    {
        TestPage testPage = new TestPage("id");
        wicketTester.startPage(testPage);

        // assert rendered field components
        wicketTester.assertComponent("form:txtName", TextField.class);
        wicketTester.assertComponent("form:department", DropDownChoice.class);
        wicketTester.assertComponent("form:employee", DropDownChoice.class);

        FormTester formTester1 = wicketTester.newFormTester("form");
        formTester1.setValue("txtName", "amit");
        formTester1.select("department", 0);
        
        
        wicketTester.executeAjaxEvent("form:department", "onchange");
        wicketTester.assertComponentOnAjaxResponse("form:employee");
                
        formTester1.select("employee", 1);
        
        formTester1.submit("submit");

        
        Assert.assertEquals(formTester1.getTextComponentValue("txtName"), 
"amit");
        
Assert.assertNotNull(wicketTester.getTagByWicketId("department").getValue());
        
Assert.assertNotNull(wicketTester.getTagByWicketId("employee").getValue());

        DropDownChoice dropDownChoice = (DropDownChoice) 
wicketTester.getComponentFromLastRenderedPage(
                "form:department");

        System.out.println(" department " + 
formTester1.getForm().get("department"));
        Assert.assertEquals((dropDownChoice.getModelObjectAsString()), "HR");
    }
