rspec controller test -- ERROR


I am trying to figure out how to pass the test for create controller

def create
    @artist =[:artist])
      flash[:notice] = "#{} dodany do bazy"
      redirect_to list_artists_path
      render :action => 'new'

    it "should redirect to artists/list after successful save" do
      artist = mock('artist')
      @artist = Artist.should_receive(:new).and_return(artist)
      post :create
      response.should redirect_to(list_artists_path)


rspec error:

Spec::Mocks::MockExpectationError in 'ArtistsController CREATE should
redirect to artists/list after successful save'
Mock 'artist' received unexpected message :save with (no args)

Finished in 0.197619 seconds

oh I would like to add that I am completely newbie to rspec.
