I would like to screenshot a website in Java. This website is based on Canvas and WebGL. Because I want to record the web viewer as PNG images. Just have no idea how to do it. I am using a Linux Debian 9 root server and it has no graphics card for info. It would have to be rendered offscreen.
Are you talking about manual (Live) or automated tests?
> Linux Debian 9 root server
Is this where your web server is installed or the machine that is used to execute your tests?
> yes with live
Not sure that I got the problem...
Live tests are executed manually and CBT's interface provides a button to take the screenshot.
It does not matter what web server serves requests as web pages are rendered on the local browser.
