There isn't really any unified test method. I think the zexy library
has some,
I looked at zexy's system to see what testing framework it used, in
the hopes
that Pd Vanilla could use the same one. But zexy is using its own
custom rig
and zexy is under the GPL, so I'm still looking for other solutions.
and someone else recently starting writing a test framework in Lua.
Hmm, it's always good to have something rather than nothing, but it
seems
desirable to have a test framework written in Tcl, C or Pd rather
than to add
Lua as a dependency.
Writing a simple testing framework for imperative code is easy.
(I've written
two and hacked on several.) Gui testing is much harder, so my
initial thought
is to just avoid it altogether and focus on imperative testing.

Hmm, wouldn't tcltest be the obvious framework to use?

But regular automated unit tests is something that we sorely need.
In the abstract, I'm interested in this. Writing some test cases
would be a
great way for me to improve my skills with both Tcl and Pd.
Any suggestions about areas of Pd that are particularly suitable for
unit
testing?
I think that audio tests would be the best way to start. Basically
generate some audio to an table/array, then compare it to the expected
result. There are a number of objects that do type-punning to speed
things up. Modern compilers with their vectorization and other
optimziations don't like type punning, so its a common source of errors.

What we do have is a farm of dev/build servers which you can get ssh
access to.

Cool, that's a great resource!
