This commit adds tests for the commands
docker diff and docker rename. Also,
it creates the mock methods of the
docker client ContainerDiff and
ContainerRename so they can
be used in the tests.
For docker diff, it covers the
cases that:
- the command runs successfully
- the client returns an error
- the container id is empty
For docker rename, it covers
the cases that:
- the command runs successfully
- the container old name is empty
- the container new name is empty
- the client returns an error
