EasyMockError

[Santhosh Kumar]

Hello All,

I am new to jUnits and Easy Mock. I have the following code

public void testHandleCreateCustomer() throws EFilialeManagerException, ServletException, IOException
     
    SCRegisterHandler handler2  =  (SCRegisterHandler) nucleus.resolveName("/de/dpag/efiliale/servicecenter/SCRegisterHandler");
  
    try {
        System.out.println("handler2::::::: " +handler2);
        assertNotNull(handler2);
     
     
        DropletInvoker invoker = new DropletInvoker(nucleus);
        DynamoHttpServletRequest request = EasyMock.createMock(DynamoHttpServletRequest.class);
        EasyMock.expect(request.setParameter("username").andReturn("dpsampleusername"));
        EasyMock.expect(request.setParameter("salutation").andReturn("Herr"));
        EasyMock.expect(request.setParameter("title").andReturn("Mr"));
        EasyMock.expect(request.setParameter("givenname").andReturn("DPFirst"));
        EasyMock.expect(request.setParameter("surname").andReturn("DPLast"));
        EasyMock.expect(request.setParameter("ekpNumber").andReturn("321"));
        EasyMock.expect(request.setParameter("salutation").andReturn("Herr"));
        EasyMock.expect(request.setParameter("kundengruppe").andReturn("DPSampleCustomerGroup"));
        EasyMock.expect(request.setParameter("location").andReturn("Berlin"));
        EasyMock.expect(request.setParameter("zip").andReturn("53173"));
        EasyMock.expect(request.setParameter("streetno").andReturn("35"));
        EasyMock.expect(request.setParameter("streetName").andReturn("sampleDPStreet"));
        EasyMock.expect(request.setParameter("companyName").andReturn("sampleDPcompany"));
        EasyMock.expect(request.setParameter("emailaddress").andReturn("sample...@gmail.com"));
       
        DynamoHttpServletResponse res = mServletTestUtils.createDynamoHttpServletResponse();
        handler2.handleCreateCustomer(request, res);
       
       
        if(handler2 != null){
            @SuppressWarnings("rawtypes")
            Class classRef = handler2.getClass();
            Method method;
         
                method = classRef.getDeclaredMethod("handleCreateCustomer",(Class[])null);
                method.setAccessible(true);
                Object object = method.invoke(handler2, (Object[])null);
               assertNotNull(object);
              }
    } catch (SecurityException exception) {
        LogFacade.error(LogFacade.BUSINESS, "Test Case Failed - SecurityException", exception);
    } catch (NoSuchMethodException exception) {
        LogFacade.error(LogFacade.BUSINESS, "Test Case Failed - NoSuchMethodException", exception);
    } catch (IllegalArgumentException exception) {
        LogFacade.error(LogFacade.BUSINESS, "Test Case Failed - IllegalArgumentException", exception);
    } catch (IllegalAccessException exception) {
        LogFacade.error(LogFacade.BUSINESS, "Test Case Failed - IllegalAccessException", exception);
    } catch (InvocationTargetException exception) {
        LogFacade.error(LogFacade.BUSINESS, "Test Case Failed - InvocationTargetException", exception);
    }
}

when I execute the tests, I get the following error.

java.lang.IllegalStateException: missing behavior definition for the preceding method call:
DynamoHttpServletRequest.getParameter("salutation")
Usage is: expect(a.foo()).andXXX()

Hi Santhosh,

I think you suppose to use get methods, instead set methods while mocking, because set method are void method and it wont return any thing.

Examaple

   EasyMock.expect(request.setParameter("username").andReturn("dpsampleusername"));

instead of this you suppose to use

   EasyMock.expect(request.getParameter("username").andReturn("dpsampleusername"));

You can't use Mock Object to save information, so you can't call expect() on set methods.

Mock object are used to simulate their behaviour when are used in other methods, so you don't need a real object but you pass a mock oject that you can control as you like, using  expect(obj.method1()).andstubReturn("yourDesiredReturn")
