What methods and criteria can be used to determine that test scenarios fully meet the specified functional requirements?

To determine that test scenarios fully meet the requirements, the following methods and criteria are used:

• Requirement Traceability: each test scenario should be linked to a specific requirement. This allows verifying that all requirements are covered by tests.

• Functionality coverage: it is checked that all functions and use cases described in the requirements are tested.

• Boundary and negative scenario coverage: tests should verify not only positive cases but also errors, exceptions, and boundary values.

• Review of test cases with analysts and developers: joint review of tests for compliance with requirements.

• Coverage matrices: tables where rows are requirements, columns are tests, and coverage is marked.

• Automated checks: if possible, automation of tests helps regularly control compliance.

Thus, full compliance is achieved through a systematic approach to traceability, coverage, and validation of test scenarios relative to requirements.
