Review comment (suggestion):
I know you can't actually run this test currently, but if you could, the test would still check for `thumbnail` and ignore `thumbnails`, so let's just do this
```suggestion
            'thumbnail': r're:^https://[\w.-]+/\w+/\w+',
            'thumbnails': 'count:2',
```
and add a `skip` key to this test with the reason as the value
