Developed by Mercury Interactive (later acquired by HP, now OpenText), was the industry-standard automated functional testing tool for enterprise applications. WinRunner 7.0 was a pivotal release, offering robust capabilities for testing desktop applications running on Windows 98, NT, 2000, and XP.
The tool was designed to test complex enterprise applications such as ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), and traditional client‑server environments. It uses a proprietary scripting language called TSL (Test Script Language), which closely resembles C, making scripts easy to read and maintain for testers with a programming background. winrunner 70 download best for pc
