WinRunner	Mercury Ltd.	Functional Testing	Expensive to charge	WinRunner's main function is to automatically repeat a fixed test process, which records a series of manual tests in the form of a script, replays in the same environment, and checks for anomalies in the same environment or where the actual results do not match. Can reduce the error caused by human factors, but also can save the test staff a lot of testing time and energy to do something else. Functional modules mainly include: GUI map, checkpoint, TSL script programming, batch testing, data-driven and other parts
LoadRunner	Mercury company	expensive	Loadrunner® is an industrial standard level load testing tool for predicting system behavior and performance. LoadRunner is able to test the entire enterprise architecture by identifying and locating problems by simulating tens of millions of users in the form of concurrent load and real-time performance monitoring. By using LoadRunner, organizations can minimize test time, optimize performance, and accelerate the release cycle of application systems. LoadRunner is an automated load testing tool for a variety of architectures that can predict system behavior and optimize system performance. The LoadRunner test object is the entire enterprise system that helps you find and discover problems faster by simulating the actual user's actions and implementing real-time performance monitoring. In addition, it can support a wide range of protocols and technologies to provide special solutions for your particular environment.
