Pass a function as a property to a Test class

Hi, I am new to the unit test framework. I am writing a simple test class with two test methods as shown below.

classdef Tester_Class < matlab.unittest.TestCase
    
    properties
        num
        expSolution1
        expSolution2
    end
    
    methods(Test)
        function squareTest(testCase, num, expSolution1)
            [actSolution, ~] = exampleFunction(num);
            testCase.verifyEqual(actSolution,expSolution1)
        end
        function rootTest(testCase, num, expSolution2)
            [~, actSolution] = exampleFunction(num);
            testCase.verifyEqual(actSolution,expSolution2)
        end
    end
end

I want the two test methods to be able to test the function exampleFunction that gives two output (square of the number and root of the number). I want to pass the number on which the function under test will work on, and the two expected output, like

Tester = Tester_Class('num', 9, 'expSolution1', 81, 'expSolution2', 3)

How can I do this?

Hi Neelabh,

From my understanding, you are trying to pass external parameters that are not defined in the test file itself. This can be done by creating an array of Parameter instances, and then use the ExternalParameters name-value argument with TestSuite creation methods such as fromClass.

You can also refer to MathWorks Documentation page for Using External Parameters in Parameterized functions.

Hope this helps!
