title: How to read configuration files in a unit test?
body: <p>I have a standard maven project layout.<br>
  Some configuration files are stored in <code>src/main/conf</code>.<br>
  Now I would like to read these files in my unit test in <code>src/test</code> (e.g. read a properties from one of those files).<br>
  How can I exactly do that?</p>
