Unit Boundary Execution Coverage Breakdown

Since R2022b

Metric ID

UnitBoundaryExecutionCoverageBreakdown

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:

  • Analyzes the overall aggregated coverage results.

  • 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 UnitBoundaryExecutionCoverageBreakdown.

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. Consequently, the compliance threshold overlay icon appears when you click Uncategorized in the Overlays section of the toolstrip.
