title: Run Test setup before all tests
body: <p>I'm using ScalaTest for BDD testing of an app.</p>
  
  <p>The <code>BeforeAndAfterAll</code> trait lets me run setup before a running the tests in a specific feature.</p>
  
  <p>But I need to run setup before any of the tests run. </p>
  
  <p>What is the simplest way to achieve this?</p>
