Requirements Condition Coverage Fragment

Since R2022b

Metric ID

RequirementsConditionCoverageFragment

Description

This metric returns the fraction of overall achieved condition coverage that comes from requirements-based tests.

Supported Artifacts

This metric collects metric results for Units in the project. To control what the dashboard classifies as a unit, see Categorize Models in Hierarchy as Components or Units.

Computation Details

The metric does not analyze coverage from tests that run in software-in-the-loop (SIL) or processor-in-the-loop (PIL) mode.

Collection

To collect data for this metric:

• In the Model Testing Dashboard, in the Achieved Coverage Ratio section, point to the widget for Requirements-Based Tests, point to the three dots, and click the run button.

• Use getMetrics with the metric ID RequirementsConditionCoverageFragment.

Collecting data for this metric loads the model file and test results files and requires a Simulink^® Coverage™ license.

Results

For this metric, instances of metric.Result return the Value as a structure that contains these fields:

• Numerator — The number of requirements-based tests that contribute to the overall achieved condition coverage.

• Denominator — The total number of tests (requirements-based and non-requirements-based) that contribute to the overall achieved condition coverage.

• Ratio — The ratio of requirements-based tests to all tests that contribute to condition coverage, calculated by dividing the Numerator by the Denominator.

Compliance Thresholds

This metric does not have predefined thresholds.
