Testing Logstash filters within another Chef wrapper cookbook

My team and I have implemented a wrapper cookbook that uses the Logstash cookbook and we would like to know if there's a simple way we can test the filters in the Logstash config within Server Spec tests in our wrapper cookbook? I've come across "Tips: Testing your filters" on the project wiki although i can't seem to figure out who to use this directly my cookbook's server spec tests. I'd appreciate any help i can get.
