The opposite of assert_select?

Question

I am writing an app where it is desirable to check if a view does not have some functionality - in particular because that functionality must be presented only to users

Answer 1

I had this problem to ensure there WASN'T a 'Delete' button, out of many buttons. The accepted answer would not work in this situation because there are already several buttons.

assert_select '.button' do |btn|
  btn.each do |b|
    assert_no_match 'Delete', b.to_s
  end
end

However, I really like GantMan's answer better!
