Web Service Tests

Automated unit and integration tests need to be added to each individual service. These should cover at least key internal components and all end-points, ideally 80% coverage.

A separate issue can be created to full integration or end-2-end where all the services are tested together.

Coverage reporting should be added and everything should run in the pipelines.

NOTE: Given the lack of time, don't worry about perfect coverage and particularly too many unit tests.
