@wenchma you should be able to just run rubucop -a to autocorrect the issues. I did it myself a while ago and committed it to master, i'm surprised they popped up again.

They look like all the same thing over and over, so the autocorrect option should be straight forward.

@wenchma can you add a spec for this? This should get you started.

[wenchma]

@jjasghar added a spec for this PR

How about below?

     let(:runner) { ChefSpec::ServerRunner.new(REDHAT_OPTS) }
     let(:node) { runner.node }
     let(:chef_run) do
       node.set['rabbitmq']['config'] = '/path/to/rabbitmq'
       runner.converge(described_recipe)
     end

@wenchma I like this, it's consistant with the other specs also. Thanks @stevecstian

[wenchma]

Maybe the above doesn't cover the default attribute, but also looks good to me ！

[stevecstian]

@wenchma Will you go with "setting attribute in let(:chef_run) block"?

[wenchma]

@stevecstian yes, will do it.
