QTP - Introduction

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.

Testing Tools:

Tools from a software testing context, can be defined as a product that supports one or more test activities right from planning, requirements, creating a build, test execution, defect logging and test analysis.

Classification of Tools

Tools can be classified based on several parameters. It includes,

  • The purpose of the tool

  • The Activities that are supported within the tool

  • The Type/level of testing it supports.

  • The Kind of licensing (open source, freeware, commercial)

  • The tecnnology used

  • Readily Integrated with Test Management Tool(Hp-Quality Center) which enables easy scheduling and Monitoring.

  • Can also be used for Mobile Application Testing.

  • Since it is a Hp product, the full support is provided by HP and by its forums for addressing technical issues.

Disadvantages:

  • Unlike Selenium, QTP works in Windows operating system only.

  • Not all versions of Browsers are supported and the testers need to wait for the patch to be released for each one of the major versions.
