Is there a Matlab tool similar to Python's Doctest?

Question

In my Python development, doctest has really helped both to

• make writing unit tests less annoying, and
• integrate usage examples with documentation.

I was wondering, is there anything like this available in the Matlab world? It doesn't have to literally use code comments as a test, but if it had those two desirable qualities, that would be great!

Answer 1

This exists now! There are three versions out there:

• An Octave-compatible version that still gets some development
• A version of Matlab-xUnit with an integrated doctest runner
• The original version from 2010, which is self-contained and emits results in TAP format

Answer 2

Not yet, but there is something to generate documentation called M2HTML.

It is very useful, and you can take a look at the examples at that page to see how wonderful results it's producing (even dependency graphs :) ).

For unit testing in MATLAB, even if there are many solutions, mlUnit was the most efficient to me.

Answer 3

There is no direct equivalent to doctest in MATLAB.

There is, however, a nice unit testing framework on the Matlab File Exchange.
