## 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)
refs #9389
- 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.
refs #9178
- we have to take care that we don't end up in circular dependencies
- e.g. API requires UrlService and UrlService needs to require the API (for requesting data)
- update the references
- we would like to get rid of the utils folder, this is/was the most complicated change
no issue
- https://github.com/mochajs/mocha/blob/master/CHANGELOG.md#400--2017-10-02
- the new `--exit` flag might be interesting at some point
> In Mocha v3.0.0 and newer, returning a Promise and calling done() will result in an exception.
- adapt teardown/setup test utility
- adapt other mixed usages of callback && Promise usage
closes#8568
- use our `urlJoin` util to concatenate the URL (not the query part of it, as this is not supported in `urlJoin`) and to prevent possible missing or double slashes, as `config.apiUrl` could be with or without trailing slash
closes#8479
- removes `markdown` field from schema
- removes `legacyMarkdown` converter
- updates tests to work with `mobiledoc` field instead of `markdown` and adapt for mobiledoc HTML output where necessary
