Hi All,

During Web Application Automation , I noticed that Execution time of the script in which complete Descriptive Programming is used is greater than execution time of the script where primarly OR and part of DP is used.

what could be reasons for better performance of teh script when OR is used thans when DP is used? Is it because when OR is used , the Object Identification is already compiled?

OR use some enhancement techniques like sourceIndex. It stores the sourceIndex when you add the object to the OR and during replay it would check if the object at that index is the one that you are looking at. If it is the one then it uses the same else it run its identification mechanism. So this saves QTP on few objects for which sourceIndex does not change during replay.

But during DP QTP has to always go through the identification algorithm and that is the reason that there is a performance difference in both

Thanks Tarun, is SourceiNdex info documented somewhere in QTP Manual ?

Well only this line

Run using source index. Uses the source index property for better performance.
