Author Class-Based Unit Tests in MATLAB

To test a MATLAB program, write a unit test using qualifications that are methods for

testing values and responding to failures.

The Test Class Definition

A test class must inherit from matlab.unittest.TestCase and contain a methods

block with the Test attribute. The methods block contains functions, each of which is a

unit test. A general, basic class definition follows.

%% Test Class Definition

classdef MyComponentTest < matlab.unittest.TestCase

%% Test Method Block

methods (Test)

% includes unit test functions

end

end

The Unit Tests

A unit test is a method that determines the correctness of a unit of software. Each unit

test is contained within a methods block. The function must accept a TestCase instance

as an input.

%% Test Class Definition

classdef MyComponentTest < matlab.unittest.TestCase

%% Test Method Block

methods (Test)

%% Test Function

function testASolution(testCase)

%% Exercise function under test

% act = the value from the function under test

%% Verify using test qualification

% exp = your expected value

% testCase.<qualification method>(act,exp);

end
