padv.builtin.task.CollectMetrics Class

R2026b

Namespace: padv.builtin.task
Superclasses: padv.Task

Task for collecting model design and testing metrics

Description

Add-On Required: This feature requires the CI/CD Automation for Simulink Check add-on.

The padv.builtin.task.CollectMetrics class provides a task that can collect model design and testing metrics using the metric.Engine API for the Model Design and Model Testing Dashboards. By default, the task collects model maintainability metrics that can help you monitor the size, architecture, and complexity of the software units and components in your project. But you can reconfigure the task to collect model testing, SIL code testing, or PIL code testing metrics by using the Dashboard property to specify which dashboard you want to collect metrics for. You can add these tasks to your process model by using the method addTask. After you add the tasks to your process model, you can run the tasks from the Process Advisor app or by using the function runprocess.

To view the source code for this built-in task, in the MATLAB^® Command Window, enter:

open padv.builtin.task.CollectMetrics

The padv.builtin.task.CollectMetrics class is a handle class.

Creation

Description

task = padv.builtin.task.CollectMetrics() creates a task for collecting model maintainability metrics like size, architecture, and complexity. These are the same metric results that the Model Maintainability Dashboard uses.

task = padv.builtin.task.CollectMetrics(Name=Value) sets certain properties using one or more name-value arguments. For example, task = padv.builtin.task.CollectMetrics(Name = "MyCollectMetricsTask") creates a task with the specified name.

You can use this syntax to set property values for InputQueries, Name, IterationQuery, InputDependencyQuery, Licenses, LaunchToolAction, and LaunchToolText.

The padv.builtin.task.CollectMetrics class also has other properties, but you cannot set those properties during task creation.

Properties

The CollectMetrics class inherits properties from padv.Task. The properties listed in Specialized Inherited Properties are padv.Task properties that the CollectMetrics task overrides.

The task also has properties for specifying Metric Collection Options. The task uses these properties to specify input arguments for the getAvailableMetricIds, execute, and generateReport functions of the metric.Engine API.

IterationQuery — Find artifacts that task iterates over

padv.builtin.query.FindDesignModels (default) | padv.Query object | name of padv.Query object

Query that finds the artifacts that the task iterates over, specified as a padv.Query object or the name of a padv.Query object. When you specify IterationQuery, the task runs one time for each artifact returned by the query. In the Process Advisor app, the artifacts returned by IterationQuery appear under task title.

For more information about task iterations, see Overview of Process Model.

Example: padv.builtin.query.FindUnits

InputDependencyQuery — Finds artifact dependencies for task inputs

padv.Query object | name of padv.Query object

Query that finds artifact dependencies for task inputs, specified as a padv.Query object or the name of a padv.Query object.

The build system runs the query specified by InputDependencyQuery to find the dependencies for the task inputs, since those dependencies can impact if task results are up-to-date.

For more information about task inputs, see Overview of Process Model.

Example: padv.builtin.query.GetDependentArtifacts

LaunchToolAction — Function that launches tool

@launchToolAction (default) | function handle

Function that launches a tool, specified as the function handle.

When you point to a task in the Process Advisor app, you can click the ellipsis (...) to see more options. For built-in tasks, you have the option to launch a tool associated with the task.

By default, the task CollectMetrics can launch the Model Maintainability Dashboard. If you specify the Dashboard property as a value other than "ModelMaintainability", the task can launch the Model Testing Dashboard instead.

Data Types: function_handle

LaunchToolText — Description of action that LaunchToolAction property performs

"Open Dashboard" (default) | string

Description of the action that the LaunchToolAction property performs, specified as a string.

Data Types: string

InputQueries — Inputs to task

padv.Query object | name of padv.Query object | array of padv.Query objects

Inputs to the task, specified as:

• a padv.Query object

• the name of padv.Query object

• an array of padv.Query objects

• an array of names of padv.Query objects

By default, the task CollectMetrics gets the current model that the task is iterating over by using the built-in query padv.builtin.query.GetIterationArtifact.

OutputDirectory — Location for standard task outputs

string(fullfile('$DEFAULTOUTPUTDIR$','$ITERATIONARTIFACT$','metrics')) (default) | string

Location for standard task outputs, specified as a string.

The built-in tasks use tokens, like $DEFAULTOUTPUTDIR$, as placeholders for dynamic path resolution during run-time. For more information, see Dynamically Resolve Paths with Tokens.

Data Types: string

Metric Collection Options

Dashboard — Dashboard metrics to collect

"ModelMaintainability" (default) | "ModelUnitPILTesting" | "ModelUnitSILTesting" | "ModelUnitTesting"

Dashboard metrics to collect, specified as one of these values:

• "ModelMaintainability" — Analyze the size, architecture, and complexity of the MATLAB, Simulink, and Stateflow artifacts in your project by using the Model Maintainability Metrics.

• "ModelUnitPILTesting" — Assess the quality and completeness of processor-in-the-loop (PIL) code testing by using the Code Testing Metrics. Collecting these metrics requires a Simulink Test license.

• "ModelUnitSILTesting" — Assess the quality and completeness of software-in-the-loop (SIL) code testing by using the Code Testing Metrics. Collecting these metrics requires a Simulink Test license.

• "ModelUnitTesting" — Assess the quality, traceability, and completeness of your models, requirements, tests, and test results by using the Model Testing Metrics. By default, collecting these metrics requires a Requirements Toolbox™ license and Simulink Test license. If you do not want to collect requirements metrics, you can specify the property IncludeRequirements as false. When IncludeRequirements is false, the task does not require a Requirements Toolbox license.

The task uses this property to get the available metrics using the function getAvailableMetricIds.

Note

If you specify a value other than "ModelMaintainability", make sure to specify the task iteration query as padv.builtin.query.FindUnits since you can only collect model testing and code testing metrics on units and not components.

Example: "ModelUnitTesting"

Installed — Filter metrics based on MathWorks^® product installation status

1 (true) (default) | 0 (false)

Filter metrics based on whether the associated MathWorks product is installed, specified as either:

• 1 (true) — Only collect metrics associated with MathWorks products installed on the current machine.

• 0 (false) — Try to collect metrics for each of the available metrics, even if the associated MathWorks products are not installed on the current machine.

Example: false

Data Types: logical

IncludeRequirements — Include requirements metrics

1 (true) (default) | 0 (false)

Include requirements metrics in model testing metric results, specified as either:

• 1 (true) — If you specified the property Dashboard as "ModelUnitTesting", the task includes requirements metrics in the model testing metric results. Collecting requirements metrics requires a Requirements Toolbox license.

• 0 (false) — The task does not collect requirements metrics. The task excludes metrics where the metric ID contains the word requirement (case insensitive).

Example: false

Data Types: logical

ReportPath — Path to report output by task

string(fullfile('$DEFAULTOUTPUTDIR$','$ITERATIONARTIFACT$','metrics')) (default) | string

Path to report output by task, specified as a string.

The task generates the report by using the function generateReport.

Data Types: string

ReportName — Name of output report

"$ITERATIONARTIFACT$_ModelMaintainability" (default) | string

Name of output report, specified as a string.

Data Types: string

ReportFormat — Format of output report

"pdf" (default) | "html-file"

Format of output report, specified as either:

• "pdf" — PDF file.

• "html-file" — HTML report.

Example: "html-file"

Data Types: string

FilteredMetrics — List of metrics to filter out

string.empty (default) | string

List of metrics to filter out, specified as a string.

For example, if you are collecting model maintainability metrics (Dashboard property specified as "ModelMaintainability"), you can skip metric collection for a metric by specifying the value of FilteredMetrics as the metric ID for the metric.

Example: "slcomp.ComponentInterfaceSignals"

Data Types: string

Methods

Specialized Public Methods

This class overrides the following inherited methods.

run	Collect metrics. Depending on the Dashboard property value, the task can collect either model maintainability metrics, model testing metrics, SIL code testing metrics, or PIL code testing metrics. Note You do not need to manually invoke this method. When you run a task using the Process Advisor app or the runprocess function, the build system automatically invokes the run method for the task. The run method inside this built-in task runs on a task object obj with task input input and returns a task result taskResult. The task result is a padv.TaskResult object that can store the pass, fail, and error information. If you inherit from this built-in task, make sure to use the same method signature inside your custom task. function taskResult = run(obj,input) ... end
dryRun	Dry run the task to validate task inputs and generate representative task outputs without actually running the task. The dryRun method inside this built-in task runs on a task object obj with task input input and returns a task result taskResult. The task result is a padv.TaskResult object that can store the pass, fail, and error information. If you inherit from this class, make sure to use the same method signature inside your custom task. function taskResult = dryRun(obj, input) ... end For more information, see Dry Run Tasks to Test Process Model.
launchToolAction	By default, the task launches the Model Maintainability Dashboard. If you specified the Dashboard property as a value other than "ModelMaintainability", the task launches the Model Testing Dashboard instead. Process Advisor uses this method when you open the tool associated with a task.

Examples

Collect Model Maintainability Metrics During Process

Add a task that can collect model maintainability metrics using the metric.Engine API for the Model Maintainability Dashboard.

Open the process model for your project. If you do not have a process model, open the Process Advisor app to automatically create a process model.

In the process model file, add the CollectMetrics task to your process model by using the addTask method. By default, the CollectMetrics task collects model maintainability metrics.

mmMetricTask = pm.addTask(padv.builtin.task.CollectMetrics());

You can reconfigure the task behavior by using the task properties. For example, to have the task return the generated metric results report as an HTML file instead of a PDF:

mmMetricTask.ReportFormat = "html-file";

Collect Model Testing and Code Testing Metrics During Process

By default, the CollectMetrics task collects model maintainability metrics. To collect different types of metrics, you can add multiple instances of the CollectMetrics to the process and reconfigure those instances to collect different metrics. For example, you can add tasks for model testing, SIL code testing, and PIL code testing metrics.

Each task instance needs a unique value for the Name property. To specify which metrics you want the task to collect, use the Dashboard property of the task. Since the dashboards collect model testing and code testing metrics for units, and not components, you need to specify the IterationQuery as padv.builtin.query.FindUnits. The other changes to the task property values give the task instances unique titles in Process Advisor and unique names for the reports that the task generates.

%% Collect Model Testing Metrics
mtMetricTask = pm.addTask(padv.builtin.task.CollectMetrics(...
    Name="ModelTestingMetrics",...
    IterationQuery=padv.builtin.query.FindUnits));
mtMetricTask.Title = "Collect Model Testing Metrics";
mtMetricTask.Dashboard = "ModelUnitTesting";
mtMetricTask.ReportName = "$ITERATIONARTIFACT$_ModelTesting";

%% Collect SIL Code Testing Metrics
stMetricTask = pm.addTask(padv.builtin.task.CollectMetrics(...
    Name="SILTestingMetrics",...
    IterationQuery=padv.builtin.query.FindUnits));
stMetricTask.Title = "Collect SIL Code Testing Metrics";
stMetricTask.Dashboard = "ModelUnitSILTesting";
stMetricTask.ReportName = "$ITERATIONARTIFACT$_SILTesting";

%% Collect PIL Code Testing Metrics
ptMetricTask = pm.addTask(padv.builtin.task.CollectMetrics(...
    Name="PILTestingMetrics",...
    IterationQuery=padv.builtin.query.FindUnits));
ptMetricTask.Title = "Collect PIL Code Testing Metrics";
ptMetricTask.Dashboard = "ModelUnitPILTesting";
ptMetricTask.ReportName = "$ITERATIONARTIFACT$_PILTesting";

You can use the other task properties to specify other task options.

To specify a preferred execution order for your tasks, you can use runsAfter. For example, if you want your process to merge test results before collecting model testing, SIL code testing, and PIL code testing metrics:

mtMetricTask.runsAfter(mergeTestTask);
stMetricTask.runsAfter(mtMetricTask);
ptMetricTask.runsAfter(stMetricTask);
