title: How to increment a value in HTML every time a selenium test case is ran
body: <p>I am testing a registration page for a website, I am a beginner in HTML scrip. I am struggling to automate the script to register as there is validation on the email address to be unique. Can anyone tell me how to increment a value in the code below. </p>
  
  <pre><code>&lt;tr&gt;
  &lt;td&gt;type&lt;/td&gt;
  &lt;td&gt;id=MainContent_Email&lt;/td&gt;
  &lt;td&gt;validtestemail@test.com&lt;/td&gt;
  </code></pre>
