Requirements-Based Testing

Requirements-based model verification, interpreting and reporting test results

Set verification link types between requirements and test artifacts such as:

Test files, test suites, and test cases in Simulink^® Test™
Simulink Design Verifier™ Verification blocks
Simulink Model Verification Library blocks

Use the Implementation status metrics to check if your requirements are implemented and address gaps in consistency. Use the Verification status metrics to check if your requirements are verified by running the tests associated with them. Review Implementation and Verification status for the requirement set in the Requirements Editor. After running tests, view a results summary and address test failures. Create justifications to exclude requirements from the Implementation and Verification status metric computation.

Classes

Topics

Review Requirements Implementation Status
Use the requirements implementation status to check how extensively requirements are implemented in your model.
Review Requirements Verification Status
Use the requirements verification status to check test and analysis results linked to your requirements.
Link Test Cases to Requirements
Associate Simulink Test test cases with requirements.
Verify Requirements with MATLAB Tests
Verify requirements by running linked MATLAB^® tests.
Track Changes to Test Cases in Requirements Editor
Track changes to test cases linked with the requirements in the Requirements Editor.
Justify Requirements
Provide justifications for your requirements.
Include Results from External Sources in Verification Status
Link and reflect the results from external sources in Requirements verification status.
Linking to a Test Script
Link a requirement to a MATLAB script.
Linking to a Result File
