Review Comment:
   Timeout annotation is missed for this test case. Could you please add that 
here as well?

Review Comment:
   In this case, if these stubbings are unnecessary, I think it's better to 
remove it to keep the code clean. What are your thoughts on that 
@szilard-nemeth @susheel-gupta?
