Ivan A. Veselovsky commented on HBASE-8584:
-------------------------------------------
Problem this is trying to solve is to provide >= 80% coverage of package
org.apache.hadoop.hbase.coprocessor in HBase branches 0.94, 0.95 and trunk.
This is the task we are assigned to solve.
As written in the suggested test description, here we only test that the class
BaseMasterObserver can be directly instantiated and that all its methods can be
invoked with default parameters without exceptions, nothing else.
Real MasterObserver implementations extending BaseMasterObserver never invoke
super.xxx(), and this is correct, because all BaseMasterObserver methods are
empty.
There is test TestMasterObserver that checks that the methods of MasterObserver
are really invoked when needed.
So, a reasonable way to cover empty methods of BaseMasterObserver is to invoke
them directly.
