I have done load testing using HP LoadRunner for one of my project and the high level details are:
Technology: Thick client Applications (VB Script), installed in the terminal servers (Windows 2003)
Application Access Mode: Users will access the application using the RDP (MSTSC –> log into RDP –> application launch in terminal server)
LoadRunner Protocols Used: RDP & HTPPS/HTML
Progress: Completed the project for few applications
Current requirement: Is there any other open source Load Testing Tool that can replace LoadRunner for this particular project.
