At one point, out of curiosity, I tried to make a C++ plugin for Geany
and the compiler choked on some keywords (`template` comes to mind, some
other too I'm sure). It probably wouldn't be a big deal to make the
needed changes though.

Yeah, I meant more with getting it all rigged up in the first place and
maybe putting some info on the wiki how to use it.

Geany uses a lot of global variables/state, so the individual functions
sometimes are pulling in context from the running instance, bypassing
function parameters and return values, that would be harder to test
The only way I can see it would actually work - keeping in mind I don't
have much experience with unit testing - is that you would have to
launch an instance of the GUI and for some functions even simulate mouse
clicks or key presses and then read the display pixels or global geany
variables/state afterwards and see if it passes the tests.

That sounds much more approachable than doing it for Geany :)
