In the past I've written test scripts outside the MATLAB xUnit Test Framework that modify the current directory or the MATLAB path so the stub functions appear first. Taking advantage of the MATLAB function name resolution rules to call something else instead.
Unfortunately, I'm still stuck developing in R2007b, haven't used the MATLAB xUnit Test Framework, and so don't have any idea if this is something the Framework or the individual test case is in a better position to handle.
Asan, this is a unit testing framework to help ensure your MATLAB programs have been written correctly and to prevent changes from introducing bugs. There is now a unit test framework included in MATLAB, and you may be interested in the following blog post describing how someone can use such a framework to ensure the quality of science & engineering:
I tried to understand 'MATLAB xUnit Test Framework' from description but unfortunately the most part I couldn't understand, can tell me is useful for what in more simple way, sorry I'm new user of MATLAB
In R2013a, a curious glitch has emerged in the behavior of the documentation. When I type 'doc', go to the home page, and click on 'Supplemental Software', I get the documentation for this package (and some others). However, the display flickers. MATLAB Support uncovered the source of the problem: the line
<meta http-equiv="REFRESH" content="0;url=xunit_product_page.html">
in the file index.html.
The fix was to delete index.html and replace it with a copy of xunit_product_page.html, renamed to index.html.
Keith - On my Mac, MATLAB xUnit passes 150 of the 151 test cases in its own test suite. (The one failure seems to be a bad test case.)
