selenium grid listening on node port instead of hub port
For my test, I am running grid and node locally on different ports. java -jar /usr/bin/selenium-server.jar -port 4444 -role hub java -jar /usr/bin/selenium-server.jar -role node -hub http://127.0.0.1:4444/grid/register -port 5556 So, the grid is running on 4444 and node is running on 5556. In my test, if i start the driver as driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub', desired_capabilities=desired_capabilities) then the test fails with the exception response = {'status': 500, 'value': '{"status":13,"value":{"class":"java.lang.NullPointerException","stackTrace":[{
