"""
This module contains integration tests meant to run against a test Mastodon instance.

You can set up a test instance locally by following this guide:
https://docs.joinmastodon.org/dev/setup/

To enable integration tests, export the following environment variables to match
your test server and database:

```
export TOOT_TEST_HOSTNAME="localhost:3000"
export TOOT_TEST_DATABASE_DSN="mastodon_development"
```
