title: Capybara testing if page has regular expression
body: <p>I'm new to RSpec and Capybara and I am trying to test if page has a time on it. 12:00 or 14:24 or 08:12 are good examples of what I am trying to test for.</p>
  
  <p>I am using the following regex:</p>
  
  <pre><code>/^\d{2}:\d{2}/
  </code></pre>
  
  <p>I am not sure how to "phrase it" in capybara to test if the page contains this regex. </p>
