Junit of Class extending WCMUsePojo using mockito

public class SomeClass extends WCMUsePojo {

@Override
public void activate() throws Exception {

SomeClassServiceImpl someServiceImpl = getSlingScriptHelper()
.getService(SomeClassServiceImpl.class);
if (null != someServiceImpl) {
someServiceImpl.someMethod(getRequest(), getResponse(), getCurrentPage());
}

}
}

On extending the class WCMUsepojo we are able to call methods like getRequest(), getResponse(), getCurrentPage(), getSlingScriptHelper()....

While writing the Junit using the Mockito  I found it difficult to write the above way. Instead  with the init method we accessed all the bindings like REQUEST, RESPONSE, CURRENT_PAGE..
SLING. The only thing we we have to do is initailize the bindings in the testActivate method
We need to Mock SlingScriptHelper,SlingBindings, the Impl class,SlingHttpServletRequest,SlingHttpServletResponse

please find the snippet

@Test
    public void testActivate() throws Exception {

        Bindings bindings = new SimpleBindings();
        WCMBindings wcmBindings = new WCMBindings();
        request = new MyRequest(slingRequest);
        when(request.getAttribute(SlingBindings.class.getName())).thenReturn(slingBindings);
        when(request.getAttribute(WCMBindings.class.getName())).thenReturn(wcmBindings);
        when(slingBindings.getSling()).thenReturn(scriptHelper);
        response = new MyResponse(slingResponse);
        when(scriptHelper.getService(SomeClassServiceImpl.class)).thenReturn(someClassService);
        bindings.put(SlingBindings.SLING, scriptHelper);
        someClassService.someMethod(request, response, currentPage);
        when(request.getResource()).thenReturn(resource);
        when(resource.adaptTo(Page.class)).thenReturn(currentPage);
        when(page.getPath()).thenReturn("/content");
        bindings.put(SlingBindings.REQUEST, request);
        bindings.put(SlingBindings.RESPONSE, response);
        bindings.put(WCMBindings.CURRENT_PAGE, page);
        SomeClass SomeClass = new SomeClass();
        SomeClass.init(bindings);

    }

    /**
     * The Class MyRequest.
     */
    private class MyRequest extends SlingHttpServletRequestWrapper {

        /**
         * Instantiates a new my request.
         *
         * @param wrappedRequest
         *            the wrapped request
         */
        public MyRequest(SlingHttpServletRequest wrappedRequest) {
            super(wrappedRequest);
        }

    }

    /**
     * The Class MyResponse.
     */
    private class MyResponse extends SlingHttpServletResponseWrapper {

        /**
         * Instantiates a new my response.
         *
         * @param wrappedRequest
         *            the wrapped response
         */
        public MyResponse(SlingHttpServletResponse wrappedResponse) {
            super(wrappedResponse);
        }

    }
