Class: sltest.testmanager.FaultSet
Namespace: sltest.testmanager

Add fault to fault set in test case

Since R2024a


specifiedFault = addSpecifiedFault(fs,modelElement,faultName)


specifiedFault = addSpecifiedFault(fs,modelElement,faultName) adds the fault faultName on the model element modelElement to the fault set fs. You can only add a fault to a fault set once. You must have Simulink® Fault Analyzer™ to use this method.

Input Arguments

expand all

Fault set, specified as a sltest.testmanager.FaultSet object.

Path of the model element, specified as a string scalar or character vector. In Simulink models, this argument is the path to a block output or input port. In Simscape™ blocks, this argument is the path to a fault-capable model subelement. In System Composer™ models, this argument is the path to a component output or input port.

Data Types: char | string

Name of the fault, specified as a string scalar or character vector.

Fault added to the fault set, returned as a sltest.testmanager.SpecifiedFault object.

Suppose you have a test file named myTestFile that contains one test case. The test uses myModel as the model under test, and the model contains a fault named myFault on the output port of a Sine Wave block. Create a test case and fault set, and add the fault to the fault set.

tf = sltest.testmanager.TestFile("myTestFile.mldatx");
ts = sltest.testmanager.TestSuite(tf,"myTestSuite");
tc = sltest.testmanager.TestCase(ts,"simulation","myTestCase");
faultSet = addFaultSet(tc);
testFault = addSpecifiedFault(faultSet,...
  "myModel/Sine Wave/Outport/1","myFault")


  • If you add faults to the model under test after you add fault sets to test cases, use the sltest.testmanager.refreshFaults function to make the faults available to the fault set.
