Roboletric - Test onClick in benutzerdefinierte Adapterelement

Question

Ich benutze Roboletric und ich möchte das onClick in das Element "viewHolder.cardView" testen.

Dies ist meine Art Adapter (das hat zwei Elemente). Ich habe bereits meine Liste und meinen Adapter erstellt, aber wie kann ich das onClick-Ereignis mit roboletric testen?

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    SimpleDateFormat dateFormat = new SimpleDateFormat(DATE_TIME_FORMAT, Locale.getDefault()); 

    if (position < mMessageList.size()) { 

     ItemHolder viewHolder; 

     if (convertView == null) { 
      convertView = LayoutInflater.from(getContext()) 
         .inflate(R.layout.item_list, parent, false); 
      viewHolder = new ItemHolder(); 
      viewHolder.cardView = (RelativeLayout) convertView.findViewById(R.id.clickable_area); 

      viewHolder.txtDate = (TextView) convertView.findViewById(R.id.message_date); 

      convertView.setTag(viewHolder); 
      } else { 
       viewHolder = (ItemHolder) convertView.getTag(); 
      } 

      final ItemModel item = mMessageList.get(position); 

      if (item != null) { 
       viewHolder.id = item.getId(); 
       if (item.getTimestamp() != null){ 
          viewHolder.txtDate.setText(dateFormat.format(item.getTimestamp())); 
      } 

      viewHolder.cardView.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         addSelection(); 
        } 
       }); 

     viewHolder.cardView.setOnLongClickListener(new View.OnLongClickListener() { 
        @Override 
        public boolean onLongClick(View view) { 
         return true; 
        } 
        }); 

        viewHolder.cardView.setSelected(item.isSelected()); 
       } 
      } 
      return convertView; 
     } 
    static class ItemHolder { 
      protected RelativeLayout cardView; 
      protected TextView txtDate; 
    }

Hier ist, was wir ähnlich tun:

SiteAdapter.ViewHolder viewHolder = adapter.onCreateViewHolder(viewGroup, -1); 
adapter.setSites(SITES); 
adapter.bindViewHolder(viewHolder, 0); 

viewHolder.rowLayout.performClick(); 

verify(busMock).send(selectedEventCaptor.capture()); 

assertThat(selectedEventCaptor.getValue().getSite()).isEqualTo(SITES.get(0)); 

wo:

@Captor 
private ArgumentCaptor<SiteSelectedEvent> selectedEventCaptor; 

@Mock 
private EventBus busMock; 

private static final List<Site> SITES = 
    Arrays.asList(new Site("1", "Test 1", new Links("one", "two")), 
       new Site("2", "Test 2", new Links("three", "four")));
