Puppeteer Support for the Cross-Browser WebDriver BiDi Standard
Puppeteer now supports the next-generation, cross-browser WebDriver BiDi standard. This new protocol makes it easy for web developers to write automated tests that work across multiple browser engines.

Version 100 in Chrome and Firefox
Chrome and Firefox will reach version 100 in a couple of months. This has the potential to cause breakage on sites that rely on identifying the browser version to perform business logic. This post covers the timeline of events, the strategies that Chrome and Firefox are taking to mitigate the impact, and how you can help.

Improving Cross-Browser Testing, Part 2: New Automation Features in Firefox Nightly
It’s clear that WebDriver needs to grow to meet the capabilities of DevTools-based automation. However, that process will take time, and we want more developers to be able to run their automated tests in Firefox today. To that end, we have shipped an experimental implementation of parts of CDP in Firefox Nightly, specifically targeting the use cases of end-to-end testing using Google’s Puppeteer, and the CDP-based features of Selenium 4.

Improving Cross-Browser Testing, Part 1: Web Application Testing Today
Testing web applications can be a challenge. At Mozilla, we see that as a call to action. With our commitment to building a better Internet, we want to provide web developers with the tools they need to build great web experiences – including great tools for testing. In this series of posts, we will explore the current web-application testing landscape and explain what Firefox is doing today to allow developers to run more kinds of tests in Firefox.

Testing Firefox more efficiently with machine learning
A browser is an enormously complex piece of software, and it's always in development. About a year ago, we asked ourselves: how could we do better? Our CI relied heavily on human intervention. What if we could instead correlate patches to tests using historical regression data? Could we use a machine learning algorithm to figure out the optimal set of tests to run? We hypothesized that we could run fewer tests to save money, get results faster, and reduce the cognitive burden on developers.

Testing Strategies for React and Redux
When the Firefox Add-ons team ported addons.mozilla.org to a single page app backed by an API, they chose React and Redux for powerful state management, delightful developer tools, and testability. Achieving the testability part wan’t as obvious, since there are competing tools and techniques. This post describes some testing strategies that are working really well.

Level Up Your Cross-Browser Testing
Today we’re announcing a special opportunity for web developers to learn how to build and automate functional browser tests — we’ve partnered with Sauce Labs to offer a special extended trial of their excellent tools, and we’ve created a custom learning resource as part of this trial. 2016: The year of web compat In 2016 […]

An easier way of using polyfills
Polyfills are a fantastic way to enable the use of modern code even while supporting legacy browsers, but currently using polyfills is too hard, so at the FT we’ve built a new service to make it easier. We’d like to invite you to use it, and help us improve it. More pictures, they said. So […]
