Can selenium python work good at background while I am doing other processes on main page?
To run selenium concurrently while i am working on other projects i just run it in a headless mode, that tends to work most of the time. 
The thing is that you have to have completed the building of the script before you do this otherwise debugging could be a nightmare if you are new or fairly new to selenium web-driver
I am running some test scripts and while it is running at the background I want to do my other jobs on excel or another web page? But sometimes I got same errors since the selenium can not find the specific field to click? What can be the reason? Is it not working well at the background?
