@dwyl we have a "Gold Standard" for examples/tutorials which must be followed without exception. Tutorials aimed at beginners should always have "complete tests" to eliminate any "excuse" people may have for not writing tests in their projects.

An example is incomplete without having 100% test coverage because it either means that there is superfluous code (which can be removed) OR there is untested code; functionality that is "magic". Both are "below expectations".

At present this example has 56% coverage: https://codecov.io/github/dwyl/phoenix-ecto-append-only-log-example?branch=master
