Performance testing is the testing technique used to determine the performance components of a particular system/ application in a specific situation. It determines how much resources are used and how much product/system is scalable, reliable, responsible, and speedy during test. This testing does not give pass or fail result, used to set the benchmark & standard of the application/system against Concurrency/Throughput, Server response time, Latency, Render response time etc. This testing is the subset of performance engineering and it is used to determine the performance issues come in the design and architecture of software product. It is very extensive, contains: Load Testing, Stress Testing, capacity testing, volume testing, endurance testing, spike testing, scalability testing and reliability testing etc.
