Isn't the js vm you're running code in kinda like a browser? Anyway, searching the web for "adobe after efects javascript" yielded this result: https://www.npmjs.com/package/after-effects https://www.npmjs.com/package/after-effects maybe it could be of use. EDIT: it seems this package acts like a connector so you could (in theory at least) npm require this package, then plug in your code, dev require a js testing framework and run some tests.
