Doctest
The Octave Doctest package
finds specially-formatted blocks of example code within documentation files.
It then executes the code and confirms the output is correct.
This can be useful as part of a testing framework or simply to ensure that
documentation stays up-to-date during software development.
To get started, here is a simple example:
function greet(user)
% Returns a greeting.
%
% >> greet World
%
% Hello, World!
disp(['Hello, ' user '!']);
end
We can test it by invoking doctest greet at the Octave prompt, which will give the following output:
greet .................................................. PASS 1/1
Summary:
PASS 1/1
1/1 targets passed, 0 without tests.
Doctest also supports Texinfo markup, which is popular in the Octave world, and it provides various toggles and switches for customizing its behavior.
The Doctest documentation contains information on all this.
Quite appropriately, Doctest can test its own documentation.
We also maintain a list of software that is using Doctest.
