MATLAB xUnit: new version available
03-Aug-2016 update: MATLAB xUnit is now in a different location. It is currently maintained by Paul Sexton.
In February 2009 I posted MATLAB xUnit, a unit testing framework, to the MATLAB Central File Exchange. I blogged about it on Feb 3, 2009, and later I wrote an article about it for the IEEE Computing in Science and Engineering journal.
I just posted an update (version 3) to the File Exchange. The update contains some changes that several people have been asking me about, including:
- Running tests stored in packages
- A verbose option for runtests (displays name and running time for each individual test case)
- Test-case files and functions can be named with "test" at the end in addition to the beginning
- Larger default floor tolerance in "almost-equal" assertion functions (makes relative floating-point comparisons a bit more forgiving for two values very close to zero)
- Fixed handling of message strings in assert functions
If you use MATLAB xUnit you might want to grab the new version.
Here's a comparison of the default output and the new verbose output from runtests when running MATLAB xUnit's own test suite.
runtests c:\Work\matlab_xunit\testsStarting test run with 147 test cases. .................... .................... .................... .................... .................... .................... .................... ....... PASSED in 4.208 seconds.
