This commit includes following cleanup tasks for coverity tool commands

1) Removed the "PrepareCommand" method from the constructor of each command and call "PrepareCommand" before runCommand.
2) Use "AssertArrayEquals" to check the expected arguments and actual arguments of the commands
3) Instead of using EasyMock, "Mockito" and "PowerMockito" are used.
4) Used "try-catch" block to test the expected exceptions
5) Added "try-finally" block for unit tests that involves writing some physical test files.
