title: Selenium fails to kill browser when test fails
body: <p>How do I set up Selenium to kill the test browser page on occasions where the test fails?</p>
  
  <p>Currently, when running Selenium test cases and a test fails, the browser page stays open and that causes problems when a large number of tests is failing. Interestingly enough, it isn't the case when the test passes. </p>
  
  <p>Any suggestion??</p>
