Unit Boundary Execution Coverage Fragment

Since R2022b

Metric ID

UnitBoundaryExecutionCoverageFragment

Description

This metric returns the fraction of overall achieved execution coverage that comes from unit-boundary tests.

Supported Artifacts

You can collect this metric for the Units in your 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 Unit-Boundary Tests, point to the three dots, and click the run button.

• Use getMetrics with the metric ID UnitBoundaryExecutionCoverageFragment.

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 unit-boundary tests that contribute to the overall achieved execution coverage.

• Denominator — The total number of tests (unit-boundary and non-unit-boundary) that contribute to the overall achieved execution coverage.

Compliance Thresholds

This metric does not have predefined thresholds.
