testingvalidation

Testingvalidation is a term used to describe the integrated practice of using testing activities to support validation of a product or system. It combines aspects of traditional testing—verification of functionality, reliability, and performance—with validation-focused activities that assess whether the product fulfills user needs, intended use, and regulatory requirements. In many quality frameworks, testingvalidation sits at the intersection of quality assurance and requirements management.

Key principles include traceability: requirements should be mapped to test cases, and evidence from tests should inform whether the product meets stakeholders' acceptance criteria. Another principle is risk-based prioritization: testingvalidation focuses resources on high-impact features and critical paths. It distinguishes between verification (are we building the product right?) and validation (are we building the right product?), emphasizing that evidence gathered through tests, simulations, or real-world pilots should support both technical and subject-matter acceptance.

Common activities involve requirements validation, test planning, test design, test execution, defect management, and results reporting. Acceptance testing, user acceptance testing, regulatory validation, field or operational testing, and pilot deployments are typical modalities used to gather validation evidence. In regulated domains such as healthcare, automotive, or aerospace, testingvalidation practices are often formalized through standards and documentation requirements.

Challenges include ambiguous requirements, changing regulations, complex integration environments, data privacy concerns, and ensuring reproducibility of results. When implemented effectively, testingvalidation provides a structured approach to demonstrate that a product meets both technical specifications and real-world usability and compliance expectations.
