ruby on rails - Stub .push method in rspec

Question

I have some code that uses .push. I want to write a unit test that tests the failure scenario of this code, but i can't figure out the syntax.

My code looks like this

   if object.groups.push(group)
    flash[:notice] = I18n.t(".success")
  else
    flash[:alert] = I18n.t(".failure")
  end

I've tried to stub out the .push method so it returns false, but it still returns true.

My stubbing attempts are below:

      object.groups.should_receive(:push).with(group).and_return(false)
  allow(object.groups).to receive(:push).with(group).and_call_original

Am i going about this the wrong way?
