The most powerful open-source load testing tool for stress and load testing. When you are working with security regulations, get your dedicated IPs from around the world to simulate user loads for your load testing. Your automated Selenium test scripts can be used for performance testing. Instead of using local data centers, create load from other regions to test for load. Amazing reporting features that display tabular and graphical data allow you to monitor app performance during tests. You can now shift left and integrate performance tests into your DevOps process using your favorite CI tool. APM tools can monitor the app infrastructure. Performance Testing is a type software testing that ensures that the application performs well under the user load. Performance testing is not intended to find bugs, but to identify performance bottlenecks. It assesses the system's quality attributes.
