I am trying to run the webdriver for opera browser under selenium 4. I am using webdriver-manager in my project. The webdriver-manager docs suggest using webdriver.Opera:
from selenium import webdriver
from webdriver_manager.opera import OperaDriverManager
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.binary_location = "C:\\Users\\USERNAME\\FOLDERLOCATION\\Opera\\VERSION\\opera.exe"
driver = webdriver.Opera(executable_path=OperaDriverManager().install(), options=options)
In this case browser doesn't even open and crashes with a SessionNotCreatedException.
However the selenium docs suggest using webdriver.Chrome():
from webdriver_manager.chrome import ChromeDriverManager
options = webdriver.ChromeOptions()
return webdriver.Chrome(service=Service(OperaDriverManager().install()), options=options)
And this also doesn't work. Does anyone know how to run Opera on selenium 4?
Update. Added stack trace
test setup failed
request = <SubRequest 'browser' for <Function test_go_to[opera]>>
@pytest.fixture(params=["opera"])

browser_name = request.param
browser = Browser.get_browser()

My current version of code:
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.binary_location = "C:\\Users\\myuser\\AppData\\Local\\Programs\\Opera\\opera.exe"
webdriver.Opera(executable_path=OperaDriverManager().install(), options=options)
CodePudding user response：
According to these discussions, opera does not support the w3c standard, and therefore has problems with selenium 4. https://github.com/operasoftware/operachromiumdriver/issues/100 https://github.com/operasoftware/operachromiumdriver/issues/96
The solution was to set the option w3c to True
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.add_experimental_option('w3c', True)
driver = webdriver.Opera(executable_path=OperaDriverManager().install(), options=options)
