Performance testing is carried out on websites and web applications in order to gather the metrics and detailed contextual information necessary for assessing production readiness, determining the speed, scalability, and throughput of the application and underlying infrastructure, and locating bottlenecks in the application architecture. The data collected can then be used throughout the performance testing life cycle:
Performance testing tools for web applications allow web developers and front-end engineers to validate the performance characteristics of a website or online service and improve the efficiency of their performance tuning efforts, shortening MTTR and accelerating product release cycles. A website load test or stress test, for example, can help performance engineers identify performance issues that surface when a website is subjected to normal to high volumes of virtual load. When executed properly, a web load test is invaluable for exposing bottlenecks in the application or backend infrastructure and optimizing overall performance.
There are a number of core activities involved in the performance testing life cycle, starting with test planning and development and ending with results analysis and reporting. But one of the most important activities of the performance testing life cycle is baselining. Establishing a reliable performance baseline lets you quickly see the impact of changes made to your application’s code or infrastructure, helping you discover performance regressions in development, detect deviations in production, and benchmark your site’s performance against your competitor’s.
Dynatrace, the leading provider of APM solutions, has developed a comprehensive digital performance monitoring platform that supports all phases of the performance testing life cycle in both development and production environments. Easily integrated into popular continuous integration and continuous delivery environments, web load testing tools give you instant, on-demand access to high-volume load, letting you implement realistic tests of your web application’s performance from the cloud.
Our synthetic web transaction monitoring solution, Dynatrace Synthetic Monitoring, extends the performance testing life cycle into production environments, allowing you to continually monitor and test your applications once they’ve gone live. With Synthetic Monitoring, your teams can proactively find and repair slow pages and broken transactions before they negatively impact the user experience.
