QTP Object identification:

Our concept is ok as all others thinks but it the original process of
identification is different .

Object identification:


QTP will identify the object in the following manner during the running.

It will understand 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.
