Get selectors of all types

Description

Use the slcoverage.Selector class with theallSelectors method to return all types of the selectors for a model object.

The slcoverage.Selector class is a handle class.

Properties

expand all

Code used to create this selector object, returned as a character vector.

Attributes:

Description of the selector, returned as a character vector. Simulink® Coverage™ creates the description based on the selector.

Attributes:

Identifier of the model element, returned as character vector of the Simulink ID or a handle.

Attributes:

Selector type, returned as a selector type of the corresponding selector.

Methods

Examples

This example shows how to get all the selectors for an And block and then add a rule to justify or exclude a selector. Metric selectors can only be justified.

Load the model and set coverage settings

modelName = 'slvnvdemo_covfilt'; load_system(modelName); set_param(modelName,'CovEnable','on','CovMetricStructuralLevel','MCDC');

First, get the block handle for the And block.

id = getSimulinkBlockHandle([modelName,'/Saturation']);

Get the selectors using the block handle.

sel = slcoverage.Selector.allSelectors(id)

sel =

1×10 heterogeneous Selector (BlockSelector, MetricSelector) array with properties:

Description
Type
Id
ConstructorCode

The block has ten selectors. You can index into each one to see their contents. In this example, you want to justify the sixth selector.

ans =

MetricSelector with properties:

 ObjectiveIndex: 2
   OutcomeIndex: 2
    Description: 'T outcome of input > upper limit in Saturate block "Saturation"'
           Type: DecisionOutcome
             Id: 'slvnvdemo_covfilt:5'
ConstructorCode: 'slcoverage.MetricSelector(slcoverage.MetricSelectorType.DecisionOutcome, 'slvnvdemo_covfilt:5', 2, 2)'

Create a justify rule, then create a filter object and add the rule to it.

rule = slcoverage.FilterRule(sel(6),'Expected result'); filt = slcoverage.Filter; filt.addRule(rule);

Save the filter and generate a coverage report.

filt.save('metrfilter'); csim = cvsim(modelName); csim.filter = 'metrfilter'; cvhtml('cov',csim,'-sRT=0');
