Model and Code Testing Metrics

Collect metrics for model testing, including requirements-based testing, and code testing

Use model and code testing metrics to assess the status of testing for software unit models. Open the Model Testing Dashboard to monitor the units and model testing artifacts in a project. As you define artifacts such as requirements, design unit models, and run unit tests, the dashboard measures the traceability and completeness of the testing artifacts for each unit. After you complete model testing, open the SIL Code Testing or PIL Code Testing dashboards to monitor the software-in-the-loop (SIL) or processor-in-the-loop (PIL) code testing results, respectively. Use the metric results to add missing traceability links, fill testing gaps, and track your testing progress. You can also use the metric API to collect metric results programmatically, such as in a continuous integration system, and save the results in a report.
