[LAD] Testdriven development with JACK?

Hi! This question could have also been asked on jack-devel, but since LAD probably has a broader audience: I recently started hacking on a jack-driven matrix mixer (goals so far: GUI, maybe network controls (OSC?), maybe LV2 host), and I wonder if there are "frameworks" for test-driven development, so I can come up with unit and acceptance tests while implementing new functionality. Has anyone ever done test-first with jack? One could start jackd in dummy mode with a random name, start some clients, wire inputs to outputs and compare the generated signal to the expected result, maybe with some fuzzy logic to allow for arbitrary delays. OTOH, if there are existing mocking libraries for jackd, things might be a bit more straight forward (provide an input buffer to be returned by jack_port_get_buffer, call the process function and check the result that's written to the output buffer). Any pointers will be highly appreciated. Cheers
