How do I do an image compare? - typeOpositive - 12-06-2010
hello folks, I have a basic question about comparing images,
Is there a way to perform a dynamic Image comparison using QTP? That is, capture a screen image during the run and after few seconds capture image of same screen and compare with first image..?
Thanks in advance!

consider using Image / bitmap check points. It shall be simple and straight forward to use them in QTP.
IMHO, requirements for comparing images changes depending on AUT (application under test). The most critical part is to decide is "how much tolerance on deviation of images is allowed?". The answer to this question will decide the strategy of comparison. Depending on the answer we might sometime end of writing our own algorithm to compare.

Thank you duggisrinivasarao. I will try to get more info on image check points...
