-------------------------------------

Hi [~dajac], 

Base on my understanding, we can't stop consumer before deleting members. This 
test was designed to validate this scenario:
 * admin client remove member from consumer group
 * admin list group to check the member is removed.

If we stop consumer before removing member, a leave group event will be sent 
and there is no way to validate the admin client trigger the member removing.
