Semi-automate. Yes, see jack-interposer [1] (also mentioned earlier in
this thread), just run the plugin in jalv or some simple jack host.

Also a good test is jack-demolition [2] feed a plugin or jack-app with
all kind of odd data (NaN, infinities, denormals) and see if it survives
(use with care to not kill your speakers).

It can go deep though.  There's Marc McCurry's Stoat -  Realtime
Function Static Analysis [2] which aid analysis.
