title: mySQL: Testing connection with query?
body: <p>I am writing some unit tests to ensure that everything is working as supposed in my application and thought it would be an good idea to write a short test script to ensure that the mySQL connection is working as intended.</p>
  
  <p>Is there any query I can run that will always output something sweet that I can verify the connection upon, without having to think about eventual stored data in the mySQL database?</p>
