What does the push option mean exactly?

What are the commands ran when you set push: false and push: true and what do they mean exactly?

if I set push to false, the action will build the dockerfile without pushing to the container registry? (that'd be great for testing).

push is the same as --push flag of build command: https://docs.docker.com/reference/cli/docker/buildx/build/#push. true will push to the registry while false does not set --push for the build command in the action which would result with nothing being exported.

so essentially with push false, it just builds the image right? so it could be used for looking for errors in the app build without pushing it to the registry.

Yes
