A test scenario is a high-level description of a testing path that validates whether a specific functionality or feature of a system works as intended. Unlike detailed test cases, which outline step-by-step actions and expected results, scenarios focus on what needs to be tested. They are usually derived from requirements documents or user stories, ensuring that the most critical features are represented and functional coverage is achieved.

Test scenarios are valuable because they provide a simple, business-focused view of the system’s behavior, making them easy to understand for both technical and non-technical stakeholders. They act as checkpoints that confirm all requirements are covered, help prioritize testing when resources are limited, and can later be broken down into test cases for detailed execution. This layered approach ensures traceability from requirements to testing activities while reducing the risk of missed functionality.

Beyond functional coverage, scenarios are also useful for exploratory, regression, and non-functional testing. In Agile, they are often created alongside user stories to align development and testing early on. Since they can be reused and adapted as the system evolves, test scenarios provide flexibility, comprehensive coverage, and a strong foundation for delivering reliable and user-friendly software.
