History of software performance testing

The ultimate guide to performance testing and software. A case study describing the experience of using these approaches for testing the performance of a system used as a gateway in a large. In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. It also shows how an application will function when the majority of its users are logged in. Performance testing checks the speed, response time, reliability, resource usage, scalability of a software program under their expected workload. From 1988 on it was seen as prevention oriented period where tests were to demonstrate that software satisfies its specification, to detect faults and to prevent faults. Software testing is an investigation conducted to provide stakeholders with information about the quality of the software product or service under test. Developers have been testing software since they first started building software following world war ii. And quality assurance as a whole has a history that stretches back much further than that, of course. It was primarily performed by the programmer who wrote the code and the object was to get the application. The purpose of performance testing is not to find functional defects but to eliminate performance bottlenecks in the software or device. There are basically four kinds of performance testing. The separation of debugging from testing was initially introduced by glenford j. It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage.

Load testing is used to study the behavior of the application under specified loads. Load testing is a type of performance testing conducted to evaluate the behavior of a system at increasing workload. Software testing can also provide an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation. Performance testing measures according to benchmarks and standards. In the early days of software development, debugging was the primary form of software test. To determine the performance specifications and document them in the test plan. Approaches to software performance testing are discussed. There are six major types of software performance testing which include load, stress, soak, spike, configuration, and isolation tests. Test techniques include the process of executing a program or application with the intent of finding software bugs, and verifying that the software product is fit for use. Performance testing is a form of software testing that focuses on how a system running the system performs under a particular load. Software testing is process of evaluation a software to detect differences between actual output and expected output. This is not about finding software bugs or defects.
