How to use the intern.config.apps function in intern

navigateToApp: function (appName, testStatusPage) {
      var self = this;

      var appUrl = getUrl.noAuth(config.servers.kibana, config.apps[appName]);
      self.debug('navigating to ' + appName + ' url: ' + navUrl);

      var doNavigation = function (url) {
        return self.tryForTime(defaultTimeout, function () {
          // since we're using hash URLs, always reload first to force re-render
          self.debug('navigate to: ' + url);
          return self.remote.get(url)
          .then(function () {
