RIDE: Screenshot-Library and Firefox, but i just get black screenshots

[alex....@w-friends.de]

Hello everyone,

i'm new to Selenium and RIDE and try to write my first test script with the final goal to compare two versions of a homepage and its sub-pages (before and after a CQ-version change). But thats another story and might be worth another question in future..

So far i get along with the setup of the several needed applications and languages (Python, wxPython, Selenium, Robotframework, Ride, …) to run RIDE based on Python and Webdriver in a MacOSX environment (atm local, later with XServer-VMs).

Nevertheless i got my first test running and by using Selenium2Library and Screenshot-Library in RIDE, i managed to write a test which does successful get screenshots with a local Webdriver driven Firefox-browser. BUT unfortunately those are always black, even with Firefox. :(

At the moment I'm running out of ideas what to try&error to achieve a stable process of those very basic function of Webdriver/Selenium (aka get proper Screenshots). 

Any hint or advice is welcome.

Best Regards,

Alex.

Great!

Managed to gain success by myself.

I used the "Take Screenshot Without Embedding"-Screenshot-Library-Command. But that command did not work, it was "Capture Page Screenshot" from the Selenium2Library.

Little bit confusing. Why is there a Screenshot-Library, if these commands would not work? 

Am i missing something?

Regards,

Alex.

Alex,

There is a difference between the two. The RF Screenshot Library [1]
takes screenshots of your full computer screen or desktop while the
"Capture Page Screenshot" keyword from the Selenium2Library takes
screenshots of only the browser page. I am not sure why the "Take
Screenshot Without Embedding" is not working in your particular case.

Ugh

Would it possible to demonstrate your problem with a dummy example. Also sending the log.html (if it doesn't contain confidential information) and the test case might share some light on your problem.

Hi Ed,

thanks for your explanation.

I'll keep that in mind ;-)
