Thanks for the contribution - however, the project is currently migrating towards a mono-repo approach (mainly under the services folder for now) which requires a little more involved approach in setting CI up properly for each project.

I unfortunately have not yet had time to set up CI, but if a PR for that approach could be set up that'd be greatly appreciated (the approach would likely be a YAML config to just running tests with npm test as a starter for each project - 3 jobs in total)
