Testing with pdf files (AI driven testing)

I don't think the sample and example on the referenced documentation work. IIRC the 

Loading PDF Documents section at the beginning does not work in docs or sample. I never did have time to finish following up. YMMV.

Thanks for the answer, we will try this out and I will be asking again if we can not get it to work - as this is the job for our colleague that is only part time here it might take a while until we actually can try it, but the link seems promising :)
