Ashish Singhi commented on HBASE-13241:
---------------------------------------

Thanks Ted for looking into it.

Thanks Srikanth for your comments.

bq. Please avoid checking whether grants are possible and verification of the 
scans in one test.
To verify scan, I will have to grant permission to a entity in the table which 
I will already do it as part of grant check. So wouldn't it duplicate the code ?

bq. Please avoid doing things like USER1_TESTGROUP_TABLE.runAs. As you can see 
from the existing testing infrastructure, we generally create an action and use 
it with verifyAllowed and verifyDenied.
I thought of doing it in that way, but in that case I will not be able to 
assert the result of scan operation output and this what is mainly required to 
test HBASE-13239

bq. In short, as already suggested, I'm looking for something similar to 
TestAccessController#testGrantRevoke for verifying whether groups belonging to 
proper groups can grant and 
TestAccessController#testPostGrantRevokeAtQualifierLevel for verifying whether 
scans work assuming grants were already involved.
As I told in my first response this will lead to duplication of code if I break 
veryification of grants/revokes whether it is possible or not and assertion of 
scan result.

As [~busbey] asked 
[here|https://issues.apache.org/jira/browse/HBASE-13241?focusedCommentId=14361909&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14361909]
 I have broke the tests at table, column family and qualifier level and added 
tests to verify scan result.
