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.TestsPerRequirementRatio]")

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.Result objects, one for each unit in the project. Use the Value 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 with these fields:
