A genuine #C06A1LKFAAC post this time: any suggestions for thorough CI testing? I have a Dockerized pipeline, so all I'm missing (I think) is a mock data source, mock target to test against, mock transform result to compare to, and a GitHub Action to bring them all together. All CI examples I've seen thus far are of the form "it builds and runs", which is fine as that goes (and certainly a good start), but I'm curious if anyone has the example of something more?
