That isn’t an exception, it’s selenium’s startup log. You’ll get that
output in the console every time you start up the driver.

Joel, thanks for your help! Any idea how can I hide/suppress it?

I’ve never been able to suppress it, although I’m sure one of the
resident geniuses would be able to work something out.
I haven’t really spent much time on it because I don’t use the console
in my user-interface, I’ve built a GUI for that so the “LOG” updates
don’t get passed through. Perhaps this is an alternative for you?

“Nice thought” I am a newbie in this platform. So not much know about
GUI. But if you give idea how to do so. I can give it a try!

Thanks

I’d suggest ignoring the LOG messages until you’ve had more time to play
with a few different approaches. You can leave displaying pretty output
until after you’ve learned more about the actual workhorse part of your
program.

At this stage of learning (and possibly every stage), “does it work” is
far more important than “does it look good”.

One of the many reasons I prefer using capybara, watir, and others
instead of running directly on selenium.

If you’re using the Windows installer for Ruby, it generally comes with
the Tk GUI package. It’s as good as any to start learning with. There
are quite a few helpful sites, here’s a basic tutorial to get you
started if you’re willing to spend the time on it. It also has a section
on installing Tk in case you don’t have it already.
