I found this on the list some time ago. You can add the
HttpServletRequest/Response in a test module.

public class PageTesterModule {
    // Ensure that there are valid HTTP request/response objects in the test

    public static void contributeRequestHandler(
            final OrderedConfiguration<RequestFilter> config,
            final RequestGlobals requestGlobals) {

        RequestFilter filter = new RequestFilter() {
            public boolean service(Request request, Response response,
RequestHandler handler) throws IOException {
                requestGlobals.storeServletRequestResponse(
                        EasyMock.createMock(HttpServletRequest.class),
                        EasyMock.createMock(HttpServletResponse.class)
                );
                return handler.service(request, response);
            }
        };
        config.add("EnsureNonNullHttpRequestAndResponse", filter, "before:*");
    }
}


If you are using PageTester you can add the module this way:


 @BeforeClass
    public void setupPageTester() {
        String appPackage = "com.bodylab.gymserver";
        String appName = "app";
        _pageTester = new PageTester(appPackage, appName,
"src/main/webapp", PageTesterModule.class);
    }
