Протокол WebDriver Bidi

These protocol commands are generated based on the current living WebDriver Bidi specification. To enable the protocol for your test make sure to have webSocketUrl: true set in your capabilities.

Use with Caution!

Browser support is not guaranteed and interfaces can change in the future. The standard is currently under development and browser vendors will add these capabilities based on their own timelines.
