Below are some situations when Descriptive Programming can be considered useful.

1] The objects in the application is dynamic in nature and need special handling to identify the object.

2] When object repository is getting huge due to the no. of objects being added.If the size of object repository increases too much then it decreases the performance of QTP while recognizing a object.

3] When you don't want to use object repository at all.Well the first question be why not object repository?consider the following scenario which would help understand why not object repository

scenario 1] suppose we have a web application that has not been developed yet.Now QTP for recording the script and adding the objects to repository needs the application to be up,that would mean waiting for the application to be deployed before we can start of making QTP scripts.But if we know the descriptions of the object that will be created then we can still start off with the script writing for testing.

scenario 2] suppose an application is 3 navigation buttons on each and every page.Let the buttons be "Cancel","Next" and "Back".Now recording action on these buttons would add 3 objects per page in the repository.For a 10 page flow this would mean 30 objects which could have been represented just by using 3 objects.So instead of adding these 30 objects to the repository we can just write 3 descriptions for the object and use it on any page.



4] Modification to a test case is needed but the object repository for the same only is Read only or in shared mode i.e ,changes may affect other scripts as well.



5]When you want to take action on similar type of object i.e, suppose we have 20 textboxes on the page and ther names are in the form txt_1,txt_2,txt_3 and so on.Now adding all 20the object repository would not be a good programming approach.There are two ways in which descriptive programming can be used.

I] By creating properties collection object for the description.

i i] By giving description in the form of string arguments.

Hi All, I have QTP installed on my machine but the application under test (AUT) is on remote desktop (i.e. I first connect to remote desktop from my machine in order to run the application). I am able to record the script successfully with QTP running on my machine and application running on remote. However, when i run the recorded script, system fails to run it and indicates me that it does not identify the object. Is it possible to record and play while QTP and AUT are not on same machine?
