Abstract
Software quality assurance (SQA) is a planned and systematic pattern of actions necessary to provide adequate confidence that a software product conforms to requirements during software development. SQA consists of methodologies and techniques of assessing the software development processes and methods, tools, and technologies used to ensure the quality of the developed software. SQA is typically achieved through the use of well-defined standard practices, including tools and processes, for quality control to ensure the integrity and reliability of software. This special issue presents new research works along these directions, and we received 21 submissions and accepted five of them after a thorough peer-review process. The acceptance rate of this special issue is around 24%. The resultant collection provides a number of useful results. These accepted papers cover a broad range of topics in the research field of SQA, including software validation, verification, and testing, SQA modeling, certification, evaluation, and improvement, SQA standards and models, SQA case studies, data analysis and risk management.
