## Contributing

[VCR.py]: https://vcrpy.readthedocs.io/

This test suite uses [VCR.py][] to record requests to Mastodon and replay them in successive runs.

If you want to add or change tests, you will need a Mastodon development server running on `http://localhost:3000`, with the default `admin` user and default password.

It also needs a test OAuth app and an additional test user to be set up by applying the provided `setup.sql` to Mastodon's database:

    psql -d mastodon_development < tests/setup.sql

Tests that send requests to Mastodon should be marked as needing VCR with the `pytest.mark.vcr` decorator.

```python
import pytest

@pytest.mark.vcr()
def test_fun_new_feature(api):
    foo = api.fun_new_feature()
    assert foo = "bar"
```
