Create Basic Parameterized Test

This example shows how to create a basic parameterized test.

Create Function to Test

In your working folder, create a function in the file sierpinski.m. This function returns

a matrix representing an image of a Sierpinski carpet fractal. It takes as input the fractal

level and an optional data type.

function carpet = sierpinski(nLevels,classname)

if nargin == 1

classname = 'single';

end

mSize = 3^nLevels;

carpet = ones(mSize,classname);

cutCarpet(1,1,mSize,nLevels) % begin recursion

function cutCarpet(x,y,s,cL)

if cL

ss = s/3; % define subsize

for lx = 0:2

for ly = 0:2

if lx == 1 && ly == 1

% remove center square

carpet(x+ss:x+2*ss-1,y+ss:y+2*ss-1) = 0;

else

% recurse

cutCarpet(x + lx*ss, y + ly*ss, ss, cL-1)

end

end

end

end

end

end

Create TestCarpet Test Class

In a file in your working folder, create a new class, TestCarpet, to test the sierpinski

function.

classdef TestCarpet < matlab.unittest.TestCase
