Cannot connect to run Selenium tests and to Chrome inspector
Opened this issue · 4 comments
When I set --remote-debugging-port=9222 using selenium-webdriver gem 3.8.0 and chromedriver-helper gem 1.1.0, which corresponds to the chromedriver-helper version 2.33.506106, I cannot get selenium to run. It errors out with Net::ReadTimeout. If I then set the port manually to 9222 in Selenium's gem files, I get the error:
Selenium::WebDriver::Error::WebDriverError:
unable to bind to locking port 9522 within 45 seconds
Is there some pointer you could give here to get crmux working with Selenium? I can boot up crmux and Chrome's inspect, but it doesn't help anything, since Selenium can't load the web page.
the error says port 9522 - is that the port crmux is listening?
@sidorares yikes. I don't have the initial code up, but I must have typo'd for that second error. I only get the Net::ReadTimeout when I put 9222 everywhere. I tried a few different ports as well as changing the --listen option for crmux. It seems that whatever crmux is listening or working on, Selenium tries 1 port after this.
Here is my selenium log (with selenium supposed to listen to 9222, and crmux running with default settings):

if you start crmux with debug switch - does it print anything when Selenium tries to connect?
it prints nothing at all to the screen :(
