This document defines assurance-related terms and establishes an organized set of concepts and relationships to form a basis for shared understanding across user communities for assurance. It provides information to users of the other parts of ISO/IEC/IEEE 15026 including the combined use of multiple parts. The essential concept introduced by ISO/IEC/IEEE 15026 (all parts) is the statement of claims in an assurance case and the support of those claims through argumentation and evidence. These… read more claims are in the context of assurance for properties of systems and software within life cycle processes for the system or software product. Assurance for a service being operated and managed on an ongoing basis is not covered in ISO/IEC/IEEE 15026 (all parts). While essential to assurance practice, details regarding exactly how to measure, demonstrate, or analyze particular properties are not covered. read less

This part of ISO/IEC/IEEE 29119 defines an efficient and consistent solution for Keyword-Driven Testing by: - giving an introduction to keyword-driven testing; - providing a reference approach to implement keyword-driven testing; - defining requirements on frameworks for keyword-driven testing to enable test engineers to share their work items, such as test cases, test data, keywords, or complete test specifications; - defining minimum requirements for tools, which are necessary to fully utilize keyword-driven testing. These requirements could apply to any tools which support the keyword-driven approach (e.g. test automation, test design and test management tools); - defining interfaces and a common data exchange format to ensure that tools from different vendors can exchange their data (e.g. test cases, test data and test results); - defining levels of hierarchical keywords, and giving advice when to use hierarchical keywords, when to use "flat" structured keywords, and describe specific types of keywords (e.g. keywords for navigation or for checking something); - providing an initial list of suggested generic technical (low level) keywords, such as "inputData" or "checkValue". These keywords can be used to specify test cases on a technical level, and may be composed to create business level keywords as required. This standard is applicable for all those who want to create keyword-driven test specifications, create corresponding frameworks, or build test automation based on keywords.
