- WinRunner is an integrated, functional testing tool for your entire enterprise. It captures, verifies and replays user interactions automatically, so that you can identify defects and ensure that business processes, which span across multiple applications and databases, work flawlessly the first time and remain reliable.

HP/Mercury Interactive's WinRunner is an automated functional GUI testing tool that allows a user to record and play back UI interactions as test scripts.

As a Functional test suit, it works together with HP QuickTest Professional and supports enterprise Quality Assurance.
HP WinRunner software is standard, functional testing software for enterprise IT applications. It captures, verifies and replays user interactions automatically, so you can identify defects and determine that your business processes work as designed.
The software implements a proprietary Test Script Language (TSL) that allows customization and parameterization of user input

How HP WinRunner works?

HP WinRunner’s intuitive recording process helps you produce robust functional tests. To create a test, HP WinRunner simply records a typical business process by emulating user actions, such as ordering an item or opening a vendor account. During recording, you can directly edit generated scripts to meet the most complex test requirements. Next, testers can add checkpoints, which compare expected and actual outcomes from the test run. HP WinRunner offers a variety of checkpoints, including test, GUI, bitmap and web links. HP WinRunner can also verify database values to determine transaction accuracy and database integrity, highlighting records that have been updated, modified, deleted and inserted. With a few mouse clicks, the DataDriver Wizard feature lets you convert a recorded business process into a datadriven test that reflects the real-life actions of multiple users. For further test enhancement, the Function Generator feature presents a quick and reliable way to program tests, while the Virtual Object Wizard feature lets you teach HP WinRunner to recognize, record and replay any unknown or custom object. As HP WinRunner executes tests, it operates the application automatically, as though a real user were performing each step in the business process. If test execution occurs after hours or in the absence of a quality assurance (QA) engineer, the Recovery Manager and Exception Handling mechanisms automatically troubleshoot unexpected events, errors and application crashes so that tests can complete smoothly. Once tests are run, HP WinRunner’s interactive report - ing tools help your team interpret results by providing detailed, easy-to-read reports that list errors and their originations. HP WinRunner lets your organization build reusable tests to repeat throughout an application’s lifecycle. Thus, if developers modify an application over time, testers do not need to modify multiple tests. Instead, they can apply changes to the Graphical User Interface (GUI) Map, a central repository of test-related information, and HP WinRunner automati - cally propagates changes to all relevant scripts.
