LoadRunner
LoadRunner is a widely used performance testing software developed by Micro Focus, designed to simulate user activity on a variety of applications and measure system performance under load. It supports a range of protocols and technologies, enabling testers to create realistic load scenarios and identify potential performance bottlenecks in both web-based and traditional software environments. LoadRunner helps in determining the scalability of a system, understanding its capacity limits, and ensuring that applications can handle anticipated traffic volumes with acceptable response times and reliability. The tool consists of multiple components, including the Virtual User Generator (VuGen) for creating test scripts, the Controller for managing and executing large-scale tests, and the Analysis tool for detailed performance reporting and analysis, making it an essential tool for ensuring the performance and stability of software systems.
