              README.md
            
          
    Capybara's README used to make a point of saying that you should use page.should have_no_content and have_no_selector when asserting the lack of some element/content (because these methods wait for the elements to disappear, if the selected Capybara driver supports waiting).
Now, Capybara's RSpec matchers have been improved so (per the documentation) saying page.should_not have_content is now functionally equivalent to saying page.should have_no_content (because it will call page.has_no_content? instead of reversing the result of page.has_content? which is not the same because of waiting).
Anywho, Capybara's code looks clear but here's a spec just to double check!  😃
