title: Installed Eclipse PDT, I do not have "Run As -> JUnit"
body: <p>I installed Eclipse PDT and now I want to run a JUnit test in a Java project. The Java perspective is used, but there are no options displayed in the Run As menu item.</p>
  
  <p>The "Run Configurations" item has the "launch new configuration" disabled.</p>
  
  <p>The tests are JUnit4 (the project compiles with junit4.jar, but not with junit3.jar).</p>
  
  <p>How can I get the "Run As -> JUnit" option?</p>
