Think of the last time you goofed up on the job. Maybe you forgot to clean out the microwave in the break room. Maybe you hit “Reply All” when you really meant “Reply.” Or maybe you nodded off during an all-hands meeting. Probably your mistake was a little less banal than any of that, but […]

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 […]

Maybe you’re not a “people person.” It’s not that you dislike other humans, but you recognize certain realities of your work. Your day job is maintaining a web application, after all, not carousing with your users. You know that accessibility is an important topic, but you haven’t been able to find the time to learn […]

If you’ve had any contact with JavaScript code, you’re probably very familiar with how to define and call functions, but are you aware of of how many different ways you can define a function? This is a common challenge of writing and maintaining tests in Test262—especially when a new feature comes into contact with any […]

Recently, I had the opportunity to contribute to a massive, meaningful effort: the open-source Web Platform Tests (WPT) project. My task was to improve WPT test coverage for areas of the HTML specification dealing with navigation —things like the details of loading new web pages, browsing around the web, and opening new windows. I didn’t […]

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 […]

August 14, 2015. Mark your calendars. That’s my next birthday. Another important date is June 18, 2015–it’s when the ECMA General Assembly will vote on and approve the 6th edition of Ecma-262 and usher in the next era of JavaScript. On that day, all those new language features we’ve been coveting/dreading will officially enter our […]

Every time I contribute to JSHint, I learn a little more about JavaScript. My most recent fantastical knowledge adventure led me to the behavior of the name attribute of function objects. JSHint has an interesting but lesser-known feature: code analysis reports. When used programatically, JSHint will return an object with some data about the code […]
