Running a Unit Test for a script

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.

That is creating a unit test in a script, but it still only checks outputs from a function file. I'm trying to find out if you can use a unit test to check a script for variable values.

[Sean de Wolski]

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

[Connor Gill]

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

This is perfect, thank you.
