As results session not created and build failed (only for selenium 4.0.0)
I would be grateful for any ideas
Solution 1:[1]
Thanks @pcalkins. Already answered in comment link
Exist issue: selenium 4.0.0 + gitlab
in gitlab-ci.yml redefine no_export variable
export no_proxy="ADD YOUR ALIAS FOR SELENIUM STANDALONE(e.g. chrome)"
services: - name: selenium/standalone-chrome:98.0 alias: chrome
Solution 2:[2]
Try:
self.wd = webdriver.Remote("http://chrome:4444", options=opt)
Instead of
self.wd = webdriver.Remote("http://chrome:4444/wd/hub", options=opt)
They changed how the interface to the grid is.
