Eric Yang commented on YARN-7202:
---------------------------------

[~jianhe] The test case are designed to be unit tests for ApiServer without 
over reaching.  It also covers the input validation in ServiceClient.  It is 
possible to write additional tests to focus on ServiceClient correctness which 
can increase test coverage.  However, I think it is easy to mistaken unit test 
verse integration test.  Without good coverage at interface level, integration 
test may not help to identify the root problems.  I can't say I am familiar 
with ServiceClient code to write unit tests for it.  I can write unit tests for 
new code that I am about to add to ServiceClient for storing Service config.  
However, it would be helpful for original author who wrote ServiceClient to add 
test code.
