title: How do I run a single test in Scala?
body: <p>I'm going through the <a href="https://github.com/scala-labs/scala-labs" rel="nofollow">scala labs</a> and I can't seem to figure out how to run a single test.</p>
  
  <p>I run <code>test</code> in <code>sbt</code> and I get 23 failing tests for me to fix. I want to run just the HelloWorldExercise.scala. How would I do this?</p>
