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

bdd.describe('visualize app', function () {
    var common;
    var remote;
    var headerPage;
    var settingsPage;
    var scenarioManager = new ScenarioManager(url.format(config.servers.elasticsearch));
    this.timeout = config.timeouts.default;

    // on setup, we create an settingsPage instance
    // that we will use for all the tests
    bdd.before(function () {
      common = new Common(this.remote);
      remote = this.remote;
      headerPage = new HeaderPage(this.remote);
      settingsPage = new SettingsPage(this.remote);
    });

    bdd.before(function () {
      var self = this;
      remote.setWindowSize(1200,800);
      // load a set of makelogs data
      common.debug('loadIfEmpty logstashFunctional ' + self.timeout);
      return scenarioManager.loadIfEmpty('logstashFunctional');

}
    func(parsed);
    return format(_.pick(parsed, 'protocol', 'hostname', 'port', 'pathname', 'query', 'hash', 'auth'));
  }

  function Common(remote) {
    this.remote = remote;
    if (remote.get.wrapper !== injectTimestampQuery) {
      this.remote.get = _.wrap(this.remote.get, injectTimestampQuery);
      remote.get.wrapper = injectTimestampQuery;
      this.remote.getCurrentUrl = _.wrap(this.remote.getCurrentUrl, removeTimestampQuery);
    }
  }


  var defaultTimeout = config.timeouts.default;

  Common.prototype = {
    constructor: Common,

    getHostPort: function getHostPort() {
      return getUrl.baseUrl(config.servers.kibana);
    },

    navigateToApp: function (appName, testStatusPage) {
      var self = this;
      // navUrl includes user:password@ for use with Shield
      // appUrl excludes user:password@ to match what getCurrentUrl returns
      var navUrl = getUrl(config.servers.kibana, config.apps[appName]);
      var appUrl = getUrl.noAuth(config.servers.kibana, config.apps[appName]);
      self.debug('navigating to ' + appName + ' url: ' + navUrl);
