The way I like to test the update method is to just ensure that the updated_at time is greater than it was before. When you do this you can change the contents of the entire instance variable and still check if everything was updated. For instance:

describe "PUT 'update/:id'" do
  it "allows an article to be updated" do
    prev_updated_at = @article.updated_at
    @attr = { :title => "new title", :content => "new content" }
    put :update, :id => @article.id, :article => @attr
    @article.reload
    @article.updated_at.should != prev_updated_at 
  end
end
