I am using the test sample shown in this page:

> **[Ruby filter plugin | Logstash Reference \[7.9\] | Elastic](https://www.elastic.co/guide/en/logstash/current/plugins-filters-ruby.html)**

But it seems this assert works

```auto
    events.size == 0

```

Because the debugging it very hard with this, if i have multiple assert, it doesnt tell me which assert failed...
