node-timing.js is a small set of helpers for working with the Navigation Timing API to identify where your application is spending its time. Useful as a function to be passed to Selenium's
executeScriptfunction.
$ npm install node-timing.jsvar timing = require('node-timing.js');

var timings;
var threshold = 2000;
before(function () {
browser.get('/');
browser.driver.executeScript(timing.getTimes).then(function (times) {
timings = times;
});
});
it('should load the page faster than ' + threshold + 'ms', function () {
expect(timings.loadTime).to.be.below(threshold);
});
