Specification

https://html.spec.whatwg.org/multipage/system-state.html#custom-handlers

Summary

The proposed `setRPHRegistrationMode` WebDriver extension command places the user agent in a mode where it will automatically accept or reject (depending on the mode) future Custom Protocol Handlers registrations. This allows full end-to-end testing of Custom Handlers API (eg, registerProtocolHandler), which normally requires user interaction to confirm the user's consent to the protocol registration.
