I also need this feature

We want to start using composite actions a lot, but also don't want to loose the ability to test locally. This feature is really needed.

Implemented in #514

@justincy Is there a readme or docs on what inputs are required for test run locally with the latest nektos/act? Maybe I'm missing some steps.

@askb: this ticket was for composite actions, your workflow appears to be a reusable workflow which was related to #826.

I'd suggest asking in gitter or opening a new ticket with a sample repository.
