How can I perform unit testing in Simulink, or preferably, Stateflow?
I'm a fan of agile software methods, including test driven development. I'm responsible for the development of safety critical control software and we're using Matlab/Simulink/Stateflow for the development of it. This toolset is selected because of the link with plant (hardware) models. (model-in-the-loop, hardware-in-the-loop)
I have found some links on Stackoverflow: Unit-testing framework for MATLAB: xunit, slunit and doctest.
EDIT: This is now much easier and getting easier all the time with the Jenkins plugin for MATLAB
ORIGINAL ANSWER:
As Craig mentioned there is indeed a framework in MATLAB introduced in R2013a. Furthermore, this framework added a TAPPlugin in R2014a which outputs the Test Anything Protocal. Using that protocol you can set up your CI build with a TAPPlugin (eg. Jenkins, TeamCity) so that the CI system can fail the build if the tests fail.
Your CI build may look like a shell command to start MATLAB and run all your tests:
/your/path/to/matlab/bin/matlab -nosplash -nodisplay -nodesktop -r "runAllMyTests"
Then the runAllMyTests creates the suite to run and runs it with the tap output being redirected to a file. You'll need to tweak specifics here, but perhaps this can help you get started:
function runAllMyTests
import matlab.unittest.TestSuite;
import matlab.unittest.TestRunner;
import matlab.unittest.plugins.TAPPlugin;
import matlab.unittest.plugins.ToFile;
try
% Create the suite and runner
suite = TestSuite.fromPackage('packageThatContainsTests', 'IncludingSubpackages', true);
runner = TestRunner.withTextOutput;
% Add the TAPPlugin directed to a file in the Jenkins workspace
tapFile = fullfile(getenv('WORKSPACE'), 'testResults.tap');
runner.addPlugin(TAPPlugin.producingOriginalFormat(ToFile(tapFile)));
runner.run(suite);
catch e;
disp(e.getReport);
exit(1);
end;
exit force;
