I'm making some changes to the logstash-input-salesforce plugin and would like to be able to see the logging generated by `@logger.debug` statements when running rspec tests.  
Currently, when rspec starts, it prints `Sending Logstash logs to null which is now configured via log4j2.properties` , but it's not obvious to me how to change that and get it to send Logstash logs to a file, for example.

Any ideas? Do I create a `log4j2.properties` somewhere? If so, where?

I'm very new to both Ruby and Logstash plugin development so this might be very obvious to a more experienced dev.

Thanks,  
Frans
