@Test public void shouldRenderTheCorrectPage() { expect(contextService.getMotechService()).andReturn(motechService); expect(motechService.getAllFacilities()).andReturn(Collections.<Facility>emptyList()); expect(motechService.getAllLanguages()).andReturn(Collections.<MessageLanguage>emptyList()); replay(contextService, motechService); ModelAndView modelAndView = controller.render(); verify(contextService, motechService); assertNotNull(modelAndView); assertEquals("/module/motechmodule/sms", modelAndView.getViewName()); WebBulkMessage message = (WebBulkMessage) modelAndView.getModelMap().get("bulkMessage"); assertNotNull(message); assertNotNull(modelAndView.getModel().get("regionMap")); assertNotNull(modelAndView.getModel().get("districtMap")); assertNotNull(modelAndView.getModel().get("facilities")); }
