Increasing test coverage

The latest PRs are failing the CI check due to the low test coverage of the code (50%). I think we need to increase this coverage, but it takes time. My proposal for this issue is to organize an agenda to improve the project's test coverage.

Yes, good call. We could first start to ensure that each PR increase the test coverage (encourage to add additional tests).
