What is Load Testing?
Load testing is the procedure of applying demand on a device or system and evaluating its response. It is performed to decide behavior of a system under normal and anticipated peak load circumstances. It helps in identifying the maximum operating capability of an app as well as the bottlenecks and determines which thing is causing degradation. When the load kept on the system is raised further than normal usage prototypes, to test the response of the system at uncommon high or peak loads, it is termed as. The load is generally so high that error conditions are the estimated result, although no clean border exists when an activity stops to be a load test and becomes a stress test.
Role of Load and Performance Testing in Product Development
Load testing allows you evaluate your website's QOS performance based on real customer nature. Almost all the load testing tools and frame-works go behind the classical load testing model. When customers come to your web site, a script recorder records the interaction and then generates relevant communication scripts. A load creator tries to replay the recorded scripts, which could probably be modified with varied test limits before replay. In the replay process, both the software and hardware statistics will be observed and gathered by the conductor, these guides include the CPU, memory; disk IO of the physical servers and the response time, throughput of the System under Test etc.
Load and performance testing scrutinizes software anticipated for a multi-user audience by subjecting the software to variable amounts of imaginary and real users while supervising performance measurements under these varied loads. Load and performance testing is generally held in a test environment familiar to the production environment before the software system is allowed to go live
