Abstract
Software testing is an essential part of software development cycle. It is considered an important activity where software is validated in compliance to requirements and specifications. Mostly, software testing is relevant to poor execution and documentation, causing additional burden on software companies or purchasers. Estimates show that 20% to 80% of total cost of software projects is spent on testing activities. Since no software can be perfect, the cost spent on testing activities is worthy especially in safety-critical systems. This paper provides an overview of ISO/IEC/IEEE 29119 software testing standard. The included parts of the standard are: concepts and definitions, test processes, test documentation, test techniques and keyword driven test.
