A script has been added to the Starterkit designed to help you quickly test your algo before uploading it to the site. You can pull the most recent starterkit and check top level README or the documentation in scripts to see how it works.
The general concept is that it will feed your algo a few gamestates fed in from a replay file and make sure your algo doesn’t crash on a random turn. It should be faster to use this method than it is to upload to our platform just to check for a small/simple syntax/logic error.
