[selenium-users] Add support for helper methods from specific browser drivers to Remote webdriver

[pavel.savchenko via Selenium Users]

Hi folks,

For example, we require access to CDP through remote driver. Currently,
we're achieve this using a subclass "hack" like so:

class CDPSupportingRemote(webdriver.Remote):
"""
Ensure driver supports `execute_cdp_cmd`

copies command from chrome to remote driver
selenium/webdriver/chrome/webdriver.py
selenium/webdriver/remote/webdriver.py
"""
execute_cdp_cmd = webdriver.Chrome.execute_cdp_cmd

def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.command_executor._commands['executeCdpCommand'] = (
'POST', '/session/$sessionId/goog/cdp/execute'
)

Is this recommended? Is there a standard way to add some of the required
capabilities to a Remote driver? If not, should there be a standard way,
perhaps using mixins, or maybe some other mechanism?

Would appreciate a discussion on the subject, perhaps some comments from
core devs as to the direction we want to take in Selenium?

Best Regards,
Pavel
