> @ottobackwards: Can we test parser chains?
I don't think so at the moment. Aggregation/chaining involves multiple
parsers, each reading/writing data from Kafka. These functions work at the
level of 1 parser and 1 `ParserRunner`. Thanks to @justinleet for my quick
education on the topic.

> Project: Metron
> Issue Type: New Feature
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Major
>
> Users need a way to test their parser configurations in a controlled
> environment. This would allow a user to tweak and test the parser
> configuration before deploying it into a live Metron cluster. The user could
> also use the REPL to understand why a particular message failed to parse
> correctly.
> This could follow the pattern of the [Profiler
> Debugger|https://github.com/apache/metron/tree/master/metron-analytics/metron-profiler#creating-profiles]
> and [Threat Triage
> Simulator|https://github.com/apache/metron/tree/master/metron-platform/metron-management#simulate-threat-triage-rules].
> This allows a user to apply canned messages against a configuration and
> inspect the output, all within the REPL.
