  /**
   * This test tests the update command.
   * <p/>
   * It works like this:
   * <p/>
   * <ol>
   * <li>Check out the files to directory getWorkingCopy().
   * <li>Check out the files to directory getUpdatingCopy().
   * <li>Change the files in getWorkingCopy().
   * <li>Commit the files in getWorkingCopy(). Note that the provider <b>must</b> not
   * use the check in command as it can be guaranteed to work as it's not yet tested.
   * <li>Use the update command in getUpdatingCopy() to assert that the files
   * that was supposed to be updated actually was updated.
   * </ol>
