Is there a way to run a unit test with a MATLAB script file testing certain variable values? I know a unit test can be used in functions, but I need a way to use it with basic script files as well.

Why would calling a function from the script not be the same as calling a script from the script?

A script has no outputs, so there wouldn't be anything for the unit test to actually check, as far as I know.

Hi Conner,

You can can just call the script from within a test function or method. Then the variables that were created in the script will be created in the test function's workspace and can just be operated on as variables in that workspace. Using the test we talked about in your other question this may look like this:

foo_AndyCampbell.m

result = 5;

Problem1Test.m

classdef Problem1Test < matlab.unittest.TestCase
  properties(ClassSetupParameter)
      student = generateClassList;
  end
    properties
        StudentFcn
    end
    methods(TestClassSetup)
        function findStudentFunction(testCase, student)
            % Look for foo_AndyCampbell, foo_ConnorGill, etc
            % and store the function handle
            testCase.StudentFcn = str2func(['foo_' student]);
        end
    end
    methods(Test)
        function testItWorks(testCase)
            testCase.StudentFcn();
            testCase.verifyEqual(result, 5)
        end
    end
  end
function students = generateClassList
students = {'AndyCampbell', 'ConnorGill'};
end
