QTP stands for QuickTest Professional, a product of Hewlett Packard (HP). This tool helps testers to perform an automated functional testing seamlessly without monitoring once script development is complete.
HP QTP uses Visual Basic Scripting (VBScript) for automating the applications. The Scripting Engine need not be installed exclusively as it is available part of the Windows OS. The Current version of VBScript is 5.8 which is available as part of Win 7. VBScript is NOT a object oriented language but a object based language.
