title: How do you share classes between test configurations using SBT
body: <p>I have followed the instructions on SBT's documentation for setting up test configurations. I have three test configurations Test, IntegrationTest, and AcceptanceTest. So my src directory looks like this:</p>
  
  <ul>
  <li>src/
  <ul>
  <li>acceptance/
  <ul>
  <li>scala/</li>
  </ul></li>
  <li>it/
  <ul>
  <li>scala/</li>
  </ul></li>
  <li>test/
  <ul>
  <li>scala/</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>My question is, how can I configure SBT to allow sharing of classes between these configurations? Example: I have a class in the "it" configuration for simplifying database setup and tear down. One of my acceptance tests in the "acceptance" configuration could make use of this class. How do I make that "it" class available to the test in "acceptance"</p>
  
  <p>Many thanks in advance.</p>
