I NEED this RIGHT NOW - awesome and thank you so much to the submitter! I'm writing my first action and there are so many facets to interacting with the runtime environment that I was testing by pushing updates. Checking my commits, I see that I committed and pushed 19 times this morning and most of them could have been avoided using act. I should also note that my Action is a bit odd since it has the local (to Docker) checkout and then calls back to the GitHub GraphQL API to make changes.
