Eclipse: wait in UI unit test

gistfile1.java

private void delay(long waitTimeMillis) {
  Display display = Display.getCurrent();
   // if UI thread then process input
  if (display != null) {
    long endTimeMillis = System.currentTimeMillis() + waitTimeMillis;
    while (System.currentTimeMillis() < endTimeMillis) {
      if (!display.readAndDispatch())
      display.sleep();
    }
    display.update();
  }

  // otherwise just wait for the delay
  else {
    try {
      Thread.sleep(waitTimeMillis);
    } catch (InterruptedException e) {
      // do nothing
    }
  }
}

// wait for jobs to finish
public void waitForJobs() {
  while (Job.getJobManager().currentJob() != null) {
    delay(1000);
