Without giving the object information into the object
repository
we can directly execute the test scripts by using DP.By
considering
following condition we will come to know how useful DP is.
1. When objects are dynamic in nature, they require special
handling
to identify the object, to handle this type of objects we
use
descriptive programming.The best example would be to click
on the
link which changes according to the user of the
application.
2. When Object Repository is getting huge in size, due to
adding No.of
objects into it, the performance of QTP will be decreased.
3. When you dont want to use the object repository at all,
then the
first question will be why not object repository.
considering some
scenarios we can understand the importance of DP.
Scenario 1. When we are having an application, which is not
yet been
developed, or in the state of run, QTP requires the
application to be
up to record the object properties to identify an object.
waiting for
the application to be up will be the waste of time, and if
we know the
flow of the application, then we can start writing DP.
Scenario 2. If we having an application, with 3 text
buttons each in
a page, adding all this 3 objects into the object
repository, in the
flow of 10 pages, a total 30 objects will be added into the
repository,
which is not a good practice, by writing 3 descriptions for
the objects
we can add them to the repository.
4. Modification for test script is required, but the
repository for the
same will be in the state of "readonly" or in "shared
mode", so modification
will impact other scripts as well.
5. When we are performing similar type of action on
objects,i.e, when
we are having an application with 20 text buttons, adding
all this
objects will not be a good practice.
