Nightwatch.js is an automated, easy to use End-to-End testing framework written in Node.js and using the W3C WebDriver API. It uses the WebDriver API to drive browsers, enabling commands and assertions on DOM elements. Nightwatch.js is used for end-to-end testing of web applications and websites, as well as for Node.js unit and integration testing. It offers a clean yet powerful syntax for quick and easy writing of tests, a built-in command-line test runner, continuous integration and...

...In-depth metrics such as: number of events bound via jQuery, calls to window.writeor complex and duplicated CSS selectors (via analyze-css). JSON as an output format. Easy integration with other nodejs projects via CommonJS module (see API docs). Metrics can be emitted from the JavaScript code of the page phantomas is run against (thanks to helper functions available in window.__phantomas). Device profiles allow phantomas to emulate mobile or tablet (by setting a proper user agent and viewport). phantomas comes as a CommonJS module that you can use in your nodejs projects. Use grunt to automate daily dev tasks, including your's application web performance.

...This would benefit the SEO and the accessibility of your website. To understand if your images are content or background, ask yourself: “would my website user like to see those images when printing out the page?”. If the answer is “yes”, then your images are content images and you should avoid using background images to display them.

Hiper is an open-source command-line tool designed for statistical analysis of web performance and page load behavior during performance testing. The tool repeatedly loads a specified webpage multiple times and gathers detailed timing metrics in order to produce more reliable performance measurements than single-run benchmarks. By averaging data across multiple page loads, Hiper helps developers understand whether performance optimizations actually improve real-world page loading behavior. ...

...Since Mocha supports promises. Just like your favorite Web browser, Zombie manages multiple open windows as tabs. New browsers start without any open tabs. As you visit the first page, Zombie will open a tab for it. All operations against the browser object operate on the currently active tab (window) and most of the time you only need to interact with that one tab. You can access it directly via browser.window. You can access all open tabs from browser.tabs. This property is an associative array, you can access each tab by its index number.

memory-stats.js is a small JavaScript utility that displays page memory usage in a style similar to stats.js. It was inspired by mrdoob’s stats.js and originally came from work related to tquery before becoming a standalone repository. The tool helps developers monitor JavaScript memory behavior directly inside a web page during development or debugging. It works by creating a MemoryStats instance, adding its display element to the DOM, and updating it regularly with requestAnimationFrame. ...
