Software performance testing has relatively vague requirements, as performance testing does not target functional quality, instead, it targets softwares structural quality. Although performance testing is nonfunctional type of testing, but in this rapidly growing fast. For example, a home user running desktop software may be interested in. Software testing iso standards many organizations around the globe develop and implement different standards to improve the quality needs of their software. Improve your software performance testing and your career. Designing and testing for performance is still not given the importance it deserves as part of the software development life cycle.
Performance testing is the type of nonfunctional testing. Performance testing, a subset of performance engineering, is a computer science practice which strives to build performance standards into the implementation. It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and resource usage. The 291191 can be considered as the foundation of ieee software testing standards.
