Hi, all I have a question when trying to write some test cases for the PR
The key functionality in my PR involves actor communication between master and worker, like the worker does something and returns the result to the master via a message, I want to test if the master can do the right thing according to the number of workers existing in the cluster and the return result from the worker, Is there any way to test this via some test cases? Thank you Best, -- Nan Zhu
