Figure 1. GigaOm Radar for Evaluating Performance Testing Tools As we noted in a previous article, the market for performance testing tools is heating up. Why? Because performance testing—which is a process that tests software applications under particular loads and provides feedback—is now seen as an integral element of a quality-first approach in cloud-native environments. Performance testing is necessary to give management and development staff information on the quality of performance of an IT business solution. Another influencing factor in the growth of performance testing is the move to shift left in DevOps. Testing can kill innovation and increase the complexity of delivering solutions. So if a test tool is difficult to use, it can become a bottleneck due to the limited number of available skilled testers. And this can mean that teams either skip performance tests or accept a reduction in quality.
