Need to write test case for dialogue list items in sling model

Hi Team,

Hope you are doing well 

Can anyone please help to write test case for this function

public List<Map<String, String>> getSliderDetail() {
  List<Map<String, String>> sliderDetailsMap=new ArrayList<>();

  try {
      Resource sliderDetail = resource.getChild("sliderDetails");
      if(sliderDetail!=null){
          for (Resource slider : sliderDetail.getChildren()) {
              Map<String,String> sliderMap=new HashMap<>();
              sliderMap.put("title",slider.getValueMap().get("title",String.class));
              sliderMap.put("description",slider.getValueMap().get("description",String.class));
              sliderDetailsMap.add(sliderMap);
          }
      }
  }catch (Exception e){
      LOG.info("\n Model Error : {} ",e.getMessage());
  }
  return sliderDetailsMap;
}

private final AemContext context = AppAemContext.newAemContext();
@Test
void getSliderDetail() {
    Resource resource = context.resourceResolver().getResource(JCR_CONTENT+"demo-aem/components/Customslider");
    Resource sliderDetail = resource.getChild("sliderDetails");
    assertNotNull(resource);
    assertNotNull(sliderDetail);
}

I have tried with this but don't know how can I pass 

Resource resource = context.resourceResolver().getResource(JCR_CONTENT+"demo-aem/components/Customslider");
In test cases 

any link or suggestion please
Thanks
