What is Smart Identification? What is its use in QTP?

Smart identification is normally used when a particular object in the script is not found or, if the the object properties have been changed over a period of time and QTP not able to recognize the object.

Smart Identification is a internal algorithm used by QTP. Smart identification feature is being enabled when an object is not recognized by QTP.

Smart identification should not be enabled during recording the script. You have to disable this feature. Once after the script is generated, then you can enable the smart identification feature.

The secret behind the smart identification is: Even though the object properties have been changed during a period of time, there will be some common points that still exist in both the versions of the object. Smart Identification catches that common property and recognizes the object. Smart identification is an important feature in QTP.
