Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [1] Software testing can determine the correctness of software for specific scenarios but cannot determine correctness for all scenarios. [2] [3] It cannot find all bugs.
This article discusses a set of tactics useful in software testing.It is intended as a comprehensive list of tactical approaches to software quality assurance (more widely colloquially known as quality assurance (traditionally called by the acronym "QA")) and general application of the test method (usually just called "testing" or sometimes "developer testing").
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 [1] It may include ensuring conformance to standards or models, such as ISO/IEC 9126 (now superseded by ISO 25010), SPICE or CMMI .
ISO/IEC/IEEE 29119 Software and systems engineering -- Software testing [1] is a series of five international standards for software testing.First developed in 2007 [2] and released in 2013, the standard "defines vocabulary, processes, documentation, techniques, and a process assessment model for testing that can be used within any software development lifecycle."
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
Test design is one of the most important prerequisites of software quality. Good test design supports: defining and improving quality related processes and procedures (quality assurance); evaluating the quality of the product with regards to customer expectations and needs (quality control); finding defects in the product (software testing).
In the context of software engineering, software quality refers to two related but distinct notions: [citation needed] Software's functional quality reflects how well it complies with or conforms to a given design, based on functional requirements or specifications. [ 1 ]
Software quality control is the set of procedures used by organizations [1] to ensure that a software product will meet its quality goals at the best value to the customer, [2] and to continually improve the organization’s ability to produce software products in the future.
