​Software quality assurance is a means and practice of monitoring all software engineering processes, methods, and work products to ensure compliance against defined standards. SQA encompasses the entire software development process, including requirements engineering, software design, coding, code reviews, source code control, software configuration management, testing, release management and software integration. Software testing is the act of examining the artefacts and the behaviour of the software and its intended functionality by validation and verification. 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.
