Software validation checks that the software product satisfies or fits the intended use (high-level checking), i.e., the software meets the user requirements, not as specification artifacts or as needs of those who will operate the software only; but, as the needs of all the stakeholders (such as users, operators, administrators, managers ...
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
The IEC 62304 standard calls out certain cautions on using software, particularly SOUP (software of unknown pedigree or provenance).The standard spells out a risk-based decision model on when the use of SOUP is acceptable, and defines testing requirements for SOUP to support a rationale on why such software should be used.
Software quality assurance (SQA) is a means and practice of monitoring all software engineering processes, methods, and work products to ensure compliance against defined standards. [1] It may include ensuring conformance to standards or models, such as ISO/IEC 9126 (now superseded by ISO 25010), SPICE or CMMI .
Software verification is a discipline of software engineering, programming languages, and theory of computation whose goal is to assure that software satisfies the expected requirements. Broad scope and classification
It is distinct from software quality assurance which encompasses processes and standards for ongoing maintenance of high quality of products, e.g. software deliverables, documentation and processes - avoiding defects. Whereas software quality control is a validation of artifacts compliance against established criteria - finding defects.
TestingCup – Polish Championship in Software Testing, Katowice, May 2016 Software testing is the act of checking whether software satisfies expectations.. Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor.
In computer programming and software testing, smoke testing (also confidence testing, sanity testing, [1] build verification test (BVT) [2] [3] [4] and build acceptance test) is preliminary testing or sanity testing to reveal simple failures severe enough to, for example, reject a prospective software release.
