I was with a team that moved from Jenkins to Actions. Jenkins has a lot of issues, but if you knew what you were doing, at least it was easy to see the history and at a glance know the project pipelines were green/healthy. It was super useful for seeing where flake was in tests or observing changes to coverage over time.
After the team migrating to actions swept though, we ran without this basic stuff for years because nobody had the time to figure out what 3rd party tool to use, money to pay for it, or capacity to re-implement the functionality. It made dealing with test failures or flake that crept in awful.
I'd like to know if my builds are getting slower over time. I'd be able to detect flaky tests automatically.
It seems basic, but I know third-party solutions exist for this. It's out of the box in Circle CI and Buildkite and feels like it should be here.
