Tests Per Requirement Distribution
R2026bMetric ID
modeltesting.TestAnalysis[slcomp.TestsPerRequirementDistribution]
Description
This metric returns a distribution showing how many requirements are linked to specific numbers of tests. The distribution groups requirements into bins based on the number of linked tests.
Use this metric to determine if requirements are linked to a disproportionate number of 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.
Collection
To collect data for this metric, execute the metric engine with the metric ID.
metric_engine = metric.Engine;
results = execute(metric_engine,"modeltesting.TestAnalysis[slcomp.TestsPerRequirementDistribution]")View the metric result values for a specific unit.
results(1).Value results(1).ScopeAlias
To collect all metrics in the modeltesting.TestAnalysis group at once,
use the group name with empty
brackets. Use the MetricID property to distinguish results from different
metrics in the
group.
results = execute(metric_engine,"modeltesting.TestAnalysis[]")Results
The metric returns an array of metric.ResultValue property of the metric result object to view the metric
result values. Use the ScopeId and ScopeAlias
properties to identify which unit the result belongs to.
The ScopeAlias property returns the name of the unit.
The Value property returns a structure array with one entry for each
bin in the distribution. Each structure has these fields:
BinEdge— Label describing the range of test counts for this bin, such as'0-4','5-9', or'>19'.BinCount— Number of requirements that fall into this bin.
