Requirements Based Testing
Requirements Based Testing is a software testing methodology where test cases are derived directly from documented requirements, specifications, or user stories to ensure the software meets its intended functionality. It focuses on validating that each requirement is correctly implemented and verifies that the system behaves as expected according to the defined criteria. This approach helps bridge the gap between stakeholder expectations and the final product by systematically testing against explicit requirements.
Developers should use Requirements Based Testing when working on projects with clear, documented requirements, such as in regulated industries (e.g., healthcare, finance) or for contract-based software development, to ensure compliance and reduce defects. It is particularly valuable in agile or waterfall methodologies to validate user stories or functional specifications early in the development cycle, improving quality and reducing rework by catching issues before deployment.
