Run MATLAB test with xunit

test-flip-functions.m

%  Once XUnit is installed, you can run this test by navigating to this directory and typing "runtests" into your MATLAB prompt.
%
%        Output Variable name should be "test_suite"
%         |           Make sure the test name either begins or ends with "test"
%         |           |
%         |           | 
function test_suite = testMyFunctions
initTestSuite;

%  Here is the first test!
%  This just takes a vector and flips it, and makes sure the fliplr function is working correctly.
%  We could easily test any function in the current path, including functions we've written.
%        Test should return nothing
%        |    Again, test starts or ends with "test"
%        |    |
%        |    |
function [] = testFliplrVector

in = [1 2 3];
out = fliplr(in);
expected_out = [3 2 1];

if ~isequal(out, expected_out)
	error('testFliplrVector:notEqual', 'Incorrect output for vector.')
end


%  This is the second test!
%  Does the same thing to test a 3x3 matrix input to fliplr.
%        The test should return nothing
%        |    Test should begin or end with "test"
%        |     |
%        |     |
function [] = testFliplrMatrix

in = magic(3);
assertEqual(fliplr(in), in(:, [3 2 1]));

%  This is the third test!
%  Let's test some attributes of the magic matrix.
function [] = testMagicMatrix

in = magic(3);
% All the rows sum to 15.
assertEqual(sum(in), [15 15 15]);
% All the columns sum to 15.
assertEqual(sum(in')', [15 15 15]');
% This is a special magic matrix, because the diagonals sum to 15 as well.
assertEqual(sum(diag(in)), 15);
