It is alternative solution to recognize Non-Standard objects

Smart identification is a mechanism provided by qtp,which is
used for identifying the objects even though some properties
are dynamically changed.

QTP uses smart identification to recognize the objects 
those are not recognized with mandotary properties of the 
object.



Smart Identification is nothing but an algorithm used by 
QTP when it is not able to recognize one of the object. A 
very generic example as per the 

QTP manual would be, A photograph of a 8 year old girl and 
boy and QTP records identification properties of that girl 
when she was 8, now when 

both are 10 years old then QTP would not be able to 
recognize the girl. But there is something that is still 
the same, that is there is only one girl in 

the photograph. So it kind of PI (Programmed intelligence) 
not AI.

When should i use SMART Identification?

Something that people don't think about too much. But the 
thing is that you should disable SI while creating your 
test cases. So that you 

are able to recognize the objects that are dynamic or 
inconsistent in their properties. When the script has been 
created, the SI should be enabled, 

so that the script does not fail in case of small changes. 
But the developer of the script should always check for the 
test results to verify if the SI 

feature was used to identify a object or not. Sometimes SI 
needs to be disabled for particular objects in the OR, this 
is advisable when you use 

SetTOProperty to change any of the TO properties of an 
object and especially ordinal identifiers like index, 
location and creationtime.

"SI" is used when the object properties like 
Mandatary,Assistive and Ordinal Identifier are not 
sufficient to recognise a particular object.

Smart identification is a mechanism used by the qtp in order
to identify the objects while normal method fails to
identify the objects.Normal method fails due to the presence
of  more no of objects of same type and also presence of
dynamically changed object(propeties are changed dynamically)
Here qtp will uses properties like base filter properties
and optional filter properties.

Smartidentification is a special mechanism provided in qtp 
to recognize the non standared objects or the objects which 
are not identified by Mandatory as well as assistive 
properties.

when Si is used?
when the QTP is not identified the objects while executing 
the script we will use SI
it will add more properties from Base fileter and Optional 
filter properties and try to identidy if at all not 
identified yet,
it will mix the basefilter and mandatory as well as 
optional and Assistive then ony one of the property is 
surely identified at last
Thanking You,

please correct me if i am wrong...,
