But the things that add complexity at least to our gitlab config are precisely things you can't really test well locally, like: - making sure you can access the AWS docker image registry, which may require particular runner configuration - making sure deploy keys are set up correctly so you can access private dependencies - testing caching behaviour - testing improvements to pipeline duration (for us, just parallelising and reordering some things meant build times decreasing from 24 to 9 minutes) - testing when exactly jobs should be triggered (e.g. stages, "only", "when", etc.) - testing the predefined variables (such as the name of the branch) - and so on
