alt Hacker Newstop tip: make a repo in your org for pushing all these nonsense changes to, test out your workflows with a dummy package being published to the repo, work out all the weird edge cases/underdocumented features of Actions
once you're done, make the actual changes in your real repo. I call the test repo 'pincushion'
We call ours "bombing-range"
We maintain an internal service that hosts two endpoints; /random-cat-picture (random >512KB image + UUID + text timestamp to evade caching) and /api/v1/generic.json which allows developers and platform folks to test out new ideas from commit to deploy behind a load balancer in an end-to-end fashion, it has saved countless headaches over the years.
