WebDriver/RemoteProtocol/News

Every few weeks we share some highlights in recent work on Remote Protocol.

2020-05-05

• Page.getFrameTree now returns all the frames of the current tab target and is now also Fission compatible.
• Page.navigate now waits until the response of the initial document request has been received and is therefore able to return errorText when navigation fails.
• See all the fixed bugs from April 7th to May 5th.

2020-04-07

• Fixed bugs between Feb 25th and April 6th
• Maja addedFirefox Nightly support to Google Puppeteer’s browser-fetching feature. This means that as of v3, Puppeteer users will have an equally convenient install+launch+connect flow for both Firefox and Chrome.
• Henrik landed several fixes and enhancements for both the Runtime.evaluate and Runtime.callFunctionOn API’s.
• Henrik added basic implementations for DOM.describeNode and DOM.resolveNode.
• We can now run Wordpress Gutenberg end-to-end tests against Firefox Nightly and we pass 52% of all the tests out of the box. To reach that status a fair amount of work has been done over the last couple of months.

2020-02-25

• Fixed bugs between Jan 15th and Feb 24th
• Henrik finished off the patch from David Burns for Page.setCookie(s).
• Henrik added support for the "clip" argument in Page.captureScreenshot
• The Puppeteer project is now running their CI jobs against Firefox Nightly in addition to Chrome

2020-01-14

• Fixed bugs between Dec 18th and Jan 14th
• 🌟 mohitsingh1930 fixed some missing default parameters in the remote agent
• 🌟 Kstheking0 refactored the remote browser-chrome tests and made the task function arguments to use an object
• Henrik implemented Network.deleteCookies and parts of Network.getCookies to allow consumers of Puppeteer to interact with site cookies.
• Henrik implemented Network.setCacheDisabled to allow ignoring the cache for each network request.
• Henrik fixed Emulation.setUserAgentOverride to only affect the current tab target.
• Henrik started the work on making the Remote Agent Fission compatible.
• You can see a demo of our Puppeteer support during the Berlin All-Hands.

2019-12-17

• Fixed bugs between Dec 4th and Dec 17th
• Maja implemented parts of Page.createIsolatedWorld and Page.addScriptToEvaluateNewDocument to enable the creation of extra JavaScript execution contexts on page load.
• Henrik implemented parts of Page.getLayoutMetrics to retrieve the layout (fixed) viewport and the full content size. Both are needed for better screenshot capabilities like capturing the full page.
• Henrik added support for Page.printToPDF to allow the current web page to be printed to a PDF file. This also includes the implementation for handling streams via IO.read and IO.close.

2019-11-05 and 2019-12-03

Introduction: The Web Predictability team (#interop) is implementing a subset of CDP in Firefox; we’ve had a working prototype for some time, and our next milestone is to provide initial cross-browser support in Google's Puppeteer (a popular Node.js library for headless browser automation).

• Fixed bugs between Nov 5th and Dec 3rd
• 🌟 Jacob Stenson removed the unnecessarily returned frameId property from the Page.loadEventFired event
• We started shipping the CDP-based remote debugging server on the Firefox Nightly release channel(see --remote-debugger flag)
• Maja added Firefox support to Puppeteer’s launcher API; users will be able to run Puppeteer with Firefox in addition to Chrome as of the next Puppeteer release.
• Andreas added a new section for Remote Debugging in about:support to expose the status if Firefox is under remote control and a visual cue in the Firefox UI when the browser is remotely controlled
• We’re steadily implementing more CDP methods on track toward our MVP
  • Andreas made it possible to use Page.reload ignoring the browser’s cache
  • Thomas Kosmas removed the unnecessarily returned timeout property from various page navigation events
  • Henrik added support for Target.activateTarget, which switches to the specified target (tab) in any of the open browser windows. That also fixed a bug in Page.bringToFront, which caused the command to not wait for the window’s “activate” and “focus” events.
  • Henrik made it possible for Page.captureScreenshot to save the captured screenshots in different formats and quality
  • Andreas added support for Security.setIgnoreCertificateErrors to allow bypassing security exceptions when loading documents with invalid or otherwise bad TLS certificates
  • Henrik added support for Emulation.setUserAgentOverride which allows clients to replace the user agent with a custom value.
