Test Case: cmdline sample commands test
=======================================

Add a test object with an IP address associated to it::

  example>add object 192.168.0.1
    Object object added, ip=192.168.0.1

Verify the object existence::

  example>add object 192.168.0.1
    Object object already exist

Show the object result by ``show`` command::

  example>show object
    Object object, ip=192.168.0.1

Verify the output matches the configuration.

Delete the object in cmdline and show the result again::

  example>del object
    Object object removed, ip=192.168.0.1

Double delete the object to verify the correctness::

  example>del object
    Bad arguments

Verify no such object exist now.::

  example>show object
    Bad arguments

Verify the hidden command ? and help command::

  example>help
