Quick Test Professional (QTP) is an automated functional Graphical User Interface (GUI) testing tool created by the HP subsidiary Mercury Interactive that allows the automation of user actions on a web or client based computer application. It is primarily used for functional regression test automation. QTP uses a scripting language built on top of VBScript to specify the test procedure, and to manipulate the objects and controls of the application under test.

QTP is UI automation software designed for testing Web-based applications running on

Microsoft Windows. Like other test automation tools, it works by identifying the objects in the application UI or a web page

and performing the desired operations on them (like mouse clicks or keyboard events); it can also be used to capture object

properties like name or handler ID etc. To perform these actions, QTP uses a scripting language built on top of VBScript to

specify the test procedure, and to manipulate the objects and controls of the application under test. To perform

sophisticated actions, users may need to manipulate the underlying VBScript.
