Unit-testing framework for MATLAB
What are the unit-testing frameworks for MATLAB out there, and how do they compare? How should I choose one for our project? What are their pros and cons?
I think the most popular framework for MATLAB is xUnit Test Framework available on File Exchange. Very flexible and well documented.
Another very recent and interesting File Exchange submission is Doctest. Not exactly unit-testing framework though, it works like doctest in Python. I haven't tried it yet, but looks very promising for simple tests embedded into function's help.
The R2013a release of MATLAB includes a fully featured unit test framework
I've been using it for >2 years. I had to do some adaptations, such as printing hyperlinks in matlab command window instead of simple text (To quickly go where the error happened). Nevertheless, it is good enough.
mlUnit. As far as I know, the only MATLAB unit test framework that:
- outputs jUnit XML reports
- comes with an Ant target to execute MATLAB and your unit tests out of the box
- with these benefits, lets you easily execute your unit tests in a Continuous Integration system, e.g. Jenkins, and monitor your test results there.
Also, mlUnit works on older MATLAB versions, e.g. R2006b and probably older. You define your test cases in test suites. A test suite is a MATLAB function file, a test case is a subfunction in that file.
Use the newest 1.6.x version. The 2.0 beta migrated an older version to MATLAB's classdef for implementation, but has not been maintained since. If you run into problems, there's an issue tracking system, because mlUnit is maintained at sourceforge.net.
