## Rule
- do not use the database in unit tests
- re-add correct unit tests if you work on something which is not tested properly (we have to bring them back at some point, but without using the database)

- https://github.com/sinonjs/sinon/blob/master/CHANGELOG.md
Breaking changes for Ghost:
- no need to create a sandbox anymore, each file get's it's own sandbox
- just require sinon and use this sandbox
- you can still create separate sandboxes with .createSandbox
- reset single stubs: use .resetHistory instead of .reset
This is a global replace for any sandbox creation.

From https://sinonjs.org/releases/v7.2.3/sandbox/
> Default sandbox
> Since sinon@5.0.0, the sinon object is a default sandbox. Unless you have a very advanced setup or need a special configuration, you probably want to just use that one.
