Hi,  
I'm new to Logstash.  
I'm working with Logstash 2.3.2.  
I'm trying to write unit tests for my configuration files.  
I wrote a simple test for a simple filter, but when I try to run them using bin\rspec, I'm getting the following error:  
GemNotFound: Could not find benchmark-ips-2.6.1.  
Do I need to install GEM and JRuby in order to run the tests?

I would assume so, yes. To test Logstash configuration files I think [https://github.com/magnusbaeck/logstash-filter-verifier](https://github.com/magnusbaeck/logstash-filter-verifier) to be both more convenient and correct than writing rspec tests (caveat: I'm the author of said tool).
