Is there an easy way to test some web page looking for some errors. I mean usually while doing web testing we want to check the display which could be very difficult to maintain. So I wanted to know if as an alternative strategy there are some practice to massively test the URLs of a website and just look for any kind of error including JS error in the console. I think it is possible using a framework like Selenium but it might be a bit overkill no ? Also the idea will be to do that on a production server, in addition to test server.
The website have some authentication so just hitting the URLs will not work.
