metric.threshold.Classification

R2026b

Classification that defines compliance criteria for threshold rule

Since R2026b

Description

A metric.threshold.Classification object represents a single compliance classification in a threshold rule. Threshold rules use classifications to categorize the metric results in the Model Testing, SIL Code Testing, and PIL Code Testing dashboards, as shown in Adjust Dashboard Thresholds to Match Your Testing Criteria.

Each classification specifies a:

• Category — A compliance status, either:

  • Compliant

  • NonCompliant

  • Warning

  • Uncategorized

• Statement — A comparison statement that determines when this classification applies.

• Summary — A description of what the classification means for the metric result.

Creation

You do not create metric.threshold.Classification objects directly. Instead, access classification objects from the Classifications property of a metric.threshold.ThresholdRule object.

Properties

Category — Compliance category

Compliant | NonCompliant | Warning | Uncategorized

Compliance category of the classification, specified as one of these values:

• Compliant — The metric result meets the threshold criteria.

• NonCompliant — The metric result does not meet the threshold criteria.

• Warning — The metric result needs review.

• Uncategorized — The metric result does not match any defined classification criteria.

Statement — Comparison statement that determines when classification applies

string

Comparison statement that determines when this classification applies, specified as a string. The statement can use relational operators (==, ~=, >, <, >=, <=), logical operators (&&, ||, ~), and arithmetic operators to compare metric result field values against expected values. Function calls are not supported.

The classifications in a threshold rule evaluate in order. Each classification with a nonempty Statement acts like an if or else-if condition. The first classification whose statement evaluates to true determines the compliance category. A classification with an empty string ("") for the Statement acts as the default else case and must be the last classification in the threshold rule.

Example: "Value.Condition == 100"

Summary — Description of classification outcome

string

Description of the classification outcome, specified as a string. The summary provides a human-readable explanation of what the classification means for the metric result.

Example: "No missing requirements-based condition coverage"

Examples

Inspect Classifications of a Threshold Rule

View the classifications of a threshold rule to understand the compliance criteria.

Copy the "ReqBasedTesting" shipping threshold set and get a threshold rule.

config = metric.config.Configuration.copyThresholdSet( ...
    SourceThresholdSetId="ReqBasedTesting", ...
    TargetThresholdSetId="MyTestingThresholds");
rule = getThresholdRule(config, ...
    ThresholdSetId="MyTestingThresholds", ...
    MetricId="modeltesting.RequirementsBasedCoverage[slcomp.CoverageRatio]", ...
    ThresholdRuleId="AchievedCondition")

rule =

  ThresholdRule with properties:

                 Id: "AchievedCondition"
     ThresholdSetId: "MyTestingThresholds"
           MetricId: "modeltesting.RequirementsBasedCoverage[slcomp.CoverageRatio]"
        Description: [1x1 metric.threshold.Description]
    Classifications: [1x2 metric.threshold.Classification]

Inspect the first classification, which defines the compliant condition.

rule.Classifications(1)

ans =

  Classification with properties:

     Category: Compliant
    Statement: "Value.Condition == 100"
      Summary: "No missing requirements-based condition coverage"

Inspect the second classification, which defines the noncompliant (default) condition. An empty Statement means this classification applies when no other statement evaluates to true.

rule.Classifications(2)

ans =

  Classification with properties:

     Category: NonCompliant
    Statement: ""
      Summary: "Some missing requirements-based condition coverage"
