WebDriver/RemoteProtocol/WebDriver BiDi

From MozillaWiki
Jump to: navigation, search

WebDriver BiDi is an extension of the WebDriver specification that offers a bidirectional communication between a webdriver compatible client and a remote end like Firefox. That means that beside sending commands to the browser and receiving responses, it will be also possible to register for certain events (e.g page load, network interception).

WebDriver BiDi Milestone 11 - In Development

Goal: Our primary focus for Milestone 11 is to clear all blockers and fully support Puppeteer. By the end of Milestone 10, we've achieved 75% compliance with the Puppeteer test suite, aiming to reach as close to 100% as possible. Additionally, we're phasing out our partial Chrome DevTools Protocol (CDP) implementation, urging users to switch to WebDriver BiDi.

WebDriver BiDi Milestone 10 - Completed March 31st, 2024

Goal: Milestone 10's foremost focus is resolving the issues hindering the achievement of full Puppeteer support. In our current "experimental" phase, we aim to gather feedback from Puppeteer users and streamline the multi-browser testing process to minimize developer effort.

WebDriver BiDi Milestone 9 - Completed December 24th, 2023

Goal: Milestone 9 maintains its focus on aligning and integrating essential functionalities from Puppeteer and Selenium. Although we managed to implement most of these high-priority features in Milestone 8, some pending APIs still need to be integrated before Puppeteer can formally announce WebDriver BiDi support for Firefox. In our dedication to staying synchronized with Selenium, we're also addressing their top priorities. As a result, this milestone is dedicated to empowering clients to introduce new features and products to their users through WebDriver BiDi.

WebDriver BiDi Milestone 8 - Completed October 01st, 2023

Goal: Milestone 8 is centered around matching and integrating crucial features from Puppeteer and Selenium. This milestone is all about enabling those clients to ship features and products using WebDriver BiDi to their users. By doing so, we hope to encourage a continuous flow of valuable user feedback and collect success narratives. This feedback is crucial for the ongoing improvement and evolution of the WebDriver BiDi project, enabling us to better align with the needs and expectations of our user base.

WebDriver BiDi Milestone 7 - Completed July 02nd, 2023

Goal: This milestone aims to expand the set of APIs supported for creating basic automated tests using WebDriver BiDi. The newly added APIs will include support for HTTP authentication, improved user interaction with pages and prompts. Additionally, efforts will be made to maintain our infrastructure for the existing WebDriver based test suites.
