For now, though, I'd like to point you to the overview video and to the documentation. A little birdie told me that more information about matlab.unittest may appear pretty soon in Loren's blog. There are lots of new capabilities in this framework. A class-level setup method is identified by using the TestClassSetup method attribute, like this: methods (TestClassSetup)ДЇunction doSomethingBeforeAllTestMethodsAreExecuted(testCase) MATLAB xUnit does not have this capability, but the new unit test framework in R2013a does.

Someone asked me just this week about enhancing MATLAB xUnit to provide for setup and teardown methods that get executed just once for all the methods in a test file, instead of being executed once for every individual test method. (I've just shown the relevant portion of the entire test file.) properties If you need to define setup and teardown methods for your test cases, here's how you do it. TestCase.verifyEqual(actSolution,expSolution) % SolverTest tests solutions to the quadratic equation

The first example shows how to write a couple of tests for a hypothetical function called quadraticSolver. Here are a few examples that I've taken from the documentation to illustrate. So an idea was born: let's make a test framework that can stand on its own, that can test our own software, that can test customer code, and that we can ship in MATLAB! They wanted to take advantage of the latest test framework design principles, and they wanted to decouple the testing machinery from the rest of our complex systems for building and releasing products. At the same time, our testing tools team was looking to modernize our testing infrastructure. The MATLAB xUnit package raised the visibility of unit testing tools in MATLAB, and its popularity helped make the case for putting something like it in MATLAB.

That became the article 'Automated Software Testing for MATLAB', published in the November/December 2009 issue. He also invited me to write up something for the IEEE magazine, Computing in Science and Engineering. Greg encouraged me to turn my fledgling tool into something real. I met Greg then, and we talked about the needs of MATLAB scientific users. At about that time, Greg Wilson (original creator of Software Carpentry) visited MathWorks to give a talk about his edited book, Beautiful Code. It hurt my brain too much.)ДЄnyway, sometime in the spring on 2008 I had something pretty basic working. (With the wisdom of hindsight, I have to say here that I don't actually recommend learning test-driven development by using test-driven development to develop a test harness. I decided that would be an excellent project with which to learn about test-driven development as well as the R2008a MATLAB language changes. Coincidentally, I had just read Kent Beck's Test-Driven Development, which included a case study on using test-driven development methods to create an xUnit-style test harness. I was interested in learning more about it.

Later, the MATLAB R2008a release included the new generation of object-oriented language features. So I wrote a simple test harness that exercised the book's examples and some of the functions.

As the 'software guy' among the three coauthors, I was responsible for overseeing the MATLAB functions in the book, including making sure that everything was working OK. This became an issue for me sometime around 2002-2003, as I was working on the first edition of Digital Image Processing Using MATLAB. Until recently, our internal testing machinery was tightly coupled to the entire system we used to build, test, and release our products, and so it was impractical to use it for small projects. I've used several generations of test frameworks created for internal use here. I learned to write unit tests when I came to MathWorks in 1993 as a new software developer. Today I want to recap how MATLAB xUnit came to be, explain what will probably happen to it, and convince its users to give the new 'official' unit test framework in R2013a a try. It is my second most popular File Exchange contribution (over 200 downloads in the last 30 days). I first wrote about it in this space in 2009. Long-time blog readers might be wondering, though, what about MATLAB xUnit? This is a unit test framework that I created and put on the File Exchange. One of the significant new capabilities in the MATLAB release is a new unit test framework ( overview video, documentation). R2013a, the latest semi-annual MathWorks product release, just went live.
