Today we’re launching Test262 Report to provide JavaScript developers with up-to-date information on the state of new and existing language features across implementations. Test262 Report is based on daily runs of Test262, the ECMA-262 (“ECMAScript” or “JavaScript”) test suite, in nightly builds of JavaScript engines, and visualizes at-a-glance status of feature implementation progress. Taking a […]

Bocoup recently facilitated an update to the WebKit project’s interaction with Test262. In this article, I’ll cover what this means for the WebKit project and the JavaScript ecosystem, as well as what exactly has been done in the WebKit project to help make this process more repeatable. Test262 is a project maintained by Ecma’s TC39. […]

We recently started working with browser implementers to improve the state of fieldset, the 21 year old feature in HTML, that provides form accessibility benefits to assistive technologies like screen readers. It suffers from a number of interoperability bugs that make it difficult for web developers to use. Here is an example form grouped with […]

On June 13, operations screeched to a halt here at Bocoup. The phones were ringing, but we didn’t answer them. Packages delivered to our door went ignored. Chicken eggs piled up. All hands were on keyboards, collaborating on the web-platform-tests project. We’ve been participating in WPT for years, largely in collaboration with the Chromium, Gecko […]

The test showed up on my desk just like any other. There I was, working with Google’s Web Platform Predictability team to find so-called “flaky” tests in the venerable Web Platform Tests project. I’d run a hundred or so at a time, over and over again, looking for any that reported inconsistent results. It was […]

Illustration by Sue Lockwood At Bocoup, we hold strong convictions about the social significance of the web platform. We want to see it expand, and we want to make sure that it remains open in all senses as it grows. Following the lead of Philippe Le Hegaret of the W3C (and in collaborations with the […]

Since starting our work on Test262, the official test suite for the ECMAScript programming language, we’ve seen our fair share of strange tests. For nerds like us, every test has the promise to teach us something new, make us laugh, or bury our head in our hands. But unlike choosing between movies, books, or 18th […]

Illustration by Sue Lockwood TC-39, the standards body that defines JavaScript, maintains a gigantic suite of tests for the language. The name of that test suite is Test262. When we started extending Test262 to cover brand new language features, we knew we were in for some surprises. Even so, we never could have anticipated the […]

In the beginning of 2015, we started another important project for the open web. Of course you haven’t forgotten, but for all the folks just joining us: Google and Bocoup teamed up to improve Test262, the official test suite for the JavaScript language. Our goal was to improve the dependability of the web platform (not […]
