I did not get very far... I use Gitlab for personal projects and love their CI/CD process ... In my company we are using Github and were excited to start using these tools for CI/CD. But when I tried to do a simple CI action that took the code in the repo and ran npm install && npm test (simple .gitlab_ci.yml on gitlab) I could not find heads or tails on how to do it... wasn't clear if it was possible with Actions or if I need a third party like CircleCi or aws or what...
