How to import block parameters into a test assessment block

I have a Simulink Mask, whick contains some parameters, when I creat a test Harness(sequence and assesment block), It allows me to create test scenarios with inports and outports, however I would also like to include Mask parameters as variables in the test scenario.

Hi Kamal,

I understand that you want to include mask parameters as variables in the test harness.

In this case, the mask parameters do not show up in the "Parameter Overrides" section of the "Simulink Test Manager" for a particular test case.

The mask parameters can be programmatically added to the parameter set to be overridden with the help of the "addParameterOverride" MATLAB function. Here is an example MATLAB code to do the same:

% Get test file -- replace 'MyTestSuite' with the .mldatx file

tf = sltest.testmanager.TestFile('\path\to\MyTestFile');

% Get test suite -- replace 'New Test Suite 1' with the name of the test suite

ts = getTestSuiteByName(tf, 'New Test Suite 1');

% Get test case -- replace 'New Test Case 1' with the name of the test case

tc = getTestCaseByName(ts, 'New Test Case 1');

% Add parameter set

ps = addParameterSet(tc, 'Name','Custom Parameter Set');

% Add parameter overrides -- replace 'MyTestModel/Subsystem' with the path to the masked subsystem

po = addParameterOverride(ps, 'gain', 2, 'MyTestModel/Subsystem');

Refer to the following documentation for further information about:

• The "addParameterOverride" function: https://www.mathworks.com/help/releases/R2023b/sltest/ref/sltest.testmanager.parameterset.addparameteroverride.html

Hope this helps.
