I tried to automate an application available under Citrixl Program Neightbourhood using QTP 9.5, but QTP does not identify the objects inside the application. Can we automat
Via citrix QTP object recognition is totaaly different. QTP on remote machines works on objects based on location and reference so it is almost impossible to automate.
For what it's worth, I have automated a CITRIX application just as you described for a large telecommunications firm in the early 2000s. I did this by getting deep inside the Windows SendMessage APIs and an optical character recognition package. You would probably be astonished by how much data was moved from one system into another using my team's CITRIX/screen-scraping "robots." I came upon this question because I was reminiscing about this project and wondering if there was still a need for this type of solution in this day and age.
QTP supports Citrix only if it is installed on the Citrix machine, it doesn't support working via the client.
For technical reasons this is because QTP needs to be able to listen to windows messages and load its DLL's into some applications which it cannot do from a different machine.
As Motti said You can't automate via Citrix client. In general Citrix client is hard to automate. I know that someone at my work played with it and he managed to catch some communication and objects that could be useful to automate tests via Citrix, but that would be separate development project to create such solution that could be very limited.
I have used Scapa Technologies for Citrix ICA or Terminal Services testing. Scapa provides an automation tool that is installed on the Citrix server. Then it has a controller that launches the citrix session, communicates with the server and starts the automation tool which calls your automation script. It actually runs on the server so it can interact with the applications controls.
Traditional tools generally do not work with applications running in remote desktop applications. The interfaces needed aren't available. Probably your only option is an image-based tool like Eggplant.
