browser = Watir::Browser.new

Answer 1

I found few problems in your code

screenshot method is not available for element object, it's available for browser object and also you need to call the method save to save the file in the destination folder. So write the following code, it would work.

Code to get the html of the page

b.html

Code to take the screenshot

b.screenshot.save("/home/user/Documents/preview.png")

Now this will save the image in the destination folder.
