Unit Testing JavaScript Without Node or a Browser

I am working on a project that contains some scripts to automate Adobe After Effects and I'd like to do some Unit Testing on those scripts. Ideally, the unit tests would be able to run in After Effects and be able to manipulate things in an After Effects project file. All of the Javascript unit testing tools I can find (mocha, jasmine, qunit, etc) seem to require node or a browser, both of which aren't applicable for my use-case. Any ideas on a framework that I could use?
