What is the Difference between Winrunner, Silkperformer, Loadrunner and Qtp
There are two ways to test different applications, manual and automated. In case of manual testing we see the application from a user’s point of view. On the other hand for automated testing, we use different tools like winrunner, silkperformer, loadrunner and Qtp. All these terms are different from each other in many respect. Let’s try to find the difference between these tools and avoid confusion of resemblance.
Winrunner
This is a load testing tool, which operates at Graphical User Interface. We can record and play the actions of users. It records the response of user, as user has actually executed these actions. Usually, it is used in combination with other applications.
Silkperformer
Silkperformer is a software application performance testing tool that checks and makes sure the performance of Web 2.0 applications like Microsoft Silverlight, Adobe Flash, AJAX/HTML. Today, Silkperformer has become a widely tool in business industry to ensure the performance of Web 2.0 applications.
Loadrunner
Loadrunner is an efficient automated testing tool for checking the performance of behavior of a system in the condition of having actual running load. This testing product is developed by Hewlett-Packard.
Qtp
QTP or QuickTest Professional is an automated testing tool that ensures the quality of feasible environment for running the software application by means of regression and functional testing. It supports the graphical user interface.
Winrunner, Silkperformer, Loadrunner and Qtp
Both Winrunner and QTP (QuickTest Professional) work on Graphical User Interface, but the difference is that Winrunner records the user actions and keeps it safe to excute in some difficulty. However, QTP is regression-based testing tool that ensures the optimal performance of software application. Loadrunner is an automated testing tool for a system behavior and performance. On the other hand, Silkperfornmer is checking tool of Web 2.0 application’s performance like Flash, Silverlight etc.
