WebDriver is a remote control interface that enables introspection and control of user agents. As such, it can help developers to verify that their websites are working and performing well with all major browsers. The protocol is standardized by the W3C and consists of two separate specifications: WebDriver classic (HTTP) and the new WebDriver BiDi (Bi-Directional).
This newsletter gives an overview of the work we’ve done as part of the Firefox 153 release cycle.
Contributions
Firefox is an open source project, and we are always happy to receive external code contributions to our WebDriver implementation. We want to give special thanks to everyone who filed issues, bugs and submitted patches.
Firefox 153, multiple WebDriver bugs were fixed by contributors:
- Khalid AlHaddad updated our codebase to use constants instead of hard-coded strings for all our session data types.
- Khalid AlHaddad improved the window manipulation commands in Marionette and WebDriver BiDi to allow individual window geometry properties, such as x, y, width, and height, to be adjusted independently.
- Sameem updated the “Take Element Screenshot” command from WebDriver Classic to crop screenshots of elements which exceed the viewport. This aligns with the specification and avoids errors when attempting to capture huge elements.
WebDriver code is written in JavaScript, Python, and Rust so any web developer can contribute!
