conditioninfo - Display condition coverage information for model object

Syntax

coverage = conditioninfo(cvdo, object)
coverage = conditioninfo(cvdo, object, ignore_descendants)
[coverage, description] = conditioninfo(cvdo, object)

Description

coverage = conditioninfo(cvdo, object) returns condition coverage results from the cvdata object cvdo for the model component specified by object. See Specifying a Model Object for more information about the object argument. The value of coverage is a two-element vector of form [covered_outcomes total_outcomes], the elements of which are defined as follows:

• covered_outcomes — the number of condition outcomes satisfied for object

• total_outcomes — the total number of condition outcomes for object

Note   coverage is empty if cvdo does not contain condition coverage results for object.

coverage = conditioninfo(cvdo, object, ignore_descendants) returns condition coverage results for object, ignoring the coverage of its descendent objects if ignore_descendants is true (i.e., 1).

[coverage, description] = conditioninfo(cvdo, object) returns condition coverage results and textual descriptions of each condition in object. description is a structure array containing the following fields:

• text — string describing a condition or the block port to which it applies

• trueCnts — number of times the condition was true in a simulation

• falseCnts — number of times the condition was false in a simulation

Specifying a Model Object

The object argument specifies an object in the Simulink model or Stateflow diagram that received decision coverage. Valid values for object include the following:

Example

The following commands open the slvnvdemo_cv_small_controller demo model, create the test specification object testObj, enable condition coverage for testObj, and execute testObj.

mdl = 'slvnvdemo_cv_small_controller';
open_system(mdl)
testObj = cvtest(mdl)
testObj.settings.condition = 1;
data = cvsim(testObj)

Afterward, issue the following commands to retrieve the condition coverage results for the Logic block (in the Gain subsystem) and determine its percentage of condition outcomes covered.

blk_handle = get_param([mdl, '/Gain/Logic'], 'Handle');
cov = conditioninfo(data, blk_handle)
percent_cov = 100 * cov(1) / cov(2)
