> Currently {{TestDecommission}} contains all test cases as well as control logic for decommission-related
tests. This is not ideal because the  decommissioning process has too many perspectives to
fit in one class. As a matter of fact the current {{TestDecommission}} class is a bit too
long, with ad hoc test cases like {{testDecommission}} and {{testDecommission2}}.
> It is better to move the decommissioning logic to {{DFSTestUtil}} so it can be called
in other unit testing classes such as {{TestReplicationPolicy}}.
