Object identification:
QTP will identify the object in the following manner during
the running.
It will under stand the script statement.
Then it releases that it needs to from some action on some
object, for that it needs some information about that
object.
For that information it will go to the object repository
and get the information from their.
With that information it will try to identify that object.
If it all the object is identified it will perform action
on that object. Here the information means object
properties.
And now the question is that how it is learning those
properties, to identify the objects.
This is the point where every one thinking his one style,
but the fact is that. That the process of learning is like
this.
There are two types of object identification that QTP
normally uses apart from the ordinal identifiers.
In general there are four types of properties that QTP
having.
1. Mandatory properties.
2. Assistive properties.
3. Base filter properties.
4. Optional filter properties.
And ordinal identifiers like location, index and creation
time.
As I told that QTP will be using two types of object
identification.
The first one is normal identification.
In this identification the learning of the properties will
be in the following way.
First the QTP will learn all the mandatory properties at a
time. And with these properties it will try to identify the
object if at all it feels these properties are sufficient
to identify the object uniquely, and then it will stop
learning and use those properties. If at all it feels these
properties are not sufficient to identify the object
uniquely, then it will learn the first assistive property.
And try to identify the object with those properties
(mandatory and first assistive property), if at all it
feels that these properties are sufficient to identify the
object uniquely then it will stop learning and use those
properties to identify the object. If it feels these
properties are not sufficient to identify the object
uniquely. Then it will learn the second assistive property
and repeat the same process till it identify the object
uniquely. If at all it fails to identify the object
uniquely by using all these properties also. Then the
ordinal identifiers come into picture. This is the process
QTP identifies the objects when the smart identification is
disable.
The second type of identification is smart identification.
In the process QTP will be learning all the mandatory, base
filter properties and optional filter properties at time.
But the identification process is as follows.
If you invoke the smart identification then also first QTP
will try to identify the object by using normal
identification process. That is the above process apart
from the ordinal identifier. Now it will not use the
ordinal identifiers. If the normal identification fails
then it will come to the smart identification. And forget
about the normal identification also all those properties
learnt in the normal identification. And now it will using
all the base filter properties at time and tries to
identify the object uniquely. If at all it feels that these
are sufficient then it will use these properties to
identify the object uniquely. Otherwise take the first
optional filter property and same process will continue as
above till the object is identified uniquely. If at all the
smart identification is also fails then it will go to use
the ordinal identifiers. This the actual process of
identification. If we have any questions regarding this
please go head and send me the e-mail to me or directly you
can contact me. only in the mentioned hours only.(8.00 PM

Answer / sreeprasad
During recording qtp looks at the object and stores it as
test object.For each test object QT learns a set of default
properties called mandatory properties,and look at the rest
of the objects to check whether this properties are enough
to uniquely identify the object. During test run,QT
searches for the run time obkects that matches with the
test object it learned while recording.

Answer / pranavi
After learning the objetc's information or properties all
the madatory properties will be saved in the object
repository, if assistive properties and ordinal identifiers
are also learnt even they will be stored in the object
repository and Base filter Properties, Optional Filter
Properties will be stored in a secrete place in object
repository which we can't see physically. Even though the
base filter and optional filter properties are stored the
qtp will not think of them first. It will think of them
only when qtp fails to identify the object using the
mandatory properties, assistive properties.
In general the Object Repository may contain the following
after the properties are learnt
1. All the Mandatory Properties (Only mandatory
properties)
2. All the mandatory and one or more Assistive
Properties
3. All the mandatory, all the Assistive
properties
4. All the mandatory, all the assistive and
ordinal idetifier
The fourth case exists if ordinal identifier is specified.
There are 2 type of identification. They are
1. Using Normal Identification
2. Using Smart Identification
1. Using Normal Identification (When there are no base
filter properties and Optional Filter Properties):
All the mandatory properties and what ever the assistive
properties qtp thought they are sufficient and which are
learnt will be stored under description properties (this
can be viewed in object identification under tools menu,
click on the object name).
Process:
Qtp will try to identify the object using normal
identification i.e. by using all the mandatory properties
and what ever the assistive properties stored when
learnt.If these details are enough the qtp will find the
object and perform the action if not sufficient it will
display an error message that "QTP cannot identify the
object object_name" when there is no ordinal identifier. If
not sufficient and if there is ordinal identifier the qtp
will find the object using ordinal identifier by forgetting
all the previous information. Even then if it is not able
to find the object it will display the error message.
2. When smart identification is enabled:
First the qtp will use description properties if they are
sufficient qtp will find the object, if it fails to
identify the object then the qtp will go the secrete place
where the base filter and optional filter properties are
stored and forgets about all the description properties and
starts the identification process freshly only by using the
base filter and optional filter properties. QTP first uses
all the base filter properties and tries to identify the
object in the application. If succeeded performs the action
but if it fails the qtp will filter the objects which are
similar and will take all the base filter properties and
1st optional filter property and tries to filter the object
among the objects which are filtered by using base filter
properties previously and will identify the unique object.
If again fails the qtp will take base filter properties,
1st and 2nd optional filter properties, by using these
details the qtp will try to find the object among the
previously filtered objects. if again fails the process
continues untill the final optional filter property. If it
still fails to identify the object then qtp will go to
ordinal identifier if it exists and tries to identify the
object, if ordinal identifier doesnot exist then qtp will
display an error message that it cannot identify the object.
If the object is identified by smart identification in test
result the description of the process how the qtp
identified the object by smart identification will be
mentioned clearly in steps.
It can be viewed as follows.
1.In test result
2.Under test iteration
Action Summary
Application_Name
Object1_name
Object2_name_smart identification
Click on the object where smart identification is specified
against the onject name. After clicking on it the
description will be displayed in a window.
