> Currently, the test cases written in hdfs-tool-test.h isn't easy to reuse.
> Primarily because the expectations are different for each HDFS tool. I
> realized this while I was creating the PR for HDFS-16260. For instance,
> passing more than one argument is erroneous to hdfs_allowSnapshot while it's
> the only valid scenario for hdfs_deleteSnapshot.
> Thus, it won't be possible to reuse the test cases without decoupling the
> expectations from the test case definitions. The solution here is to move the
> expectations to the corresponding mock classes and invoke the call to set
> them up in the test cases after the creation of mock instances.
