Logstash Filter Verifier works great for testing even complex Logstash Pipelines.
However it seems that it currently does not support testing of multiline messages properly.
Whenever I add a "\n" into the message string, it will increase the number of events, which will cause the tests to fail like this:
Testcase failed, continuing with the rest: Expected 3 event(s), got 5 instead.
How can I test multiline messages (eg. messages including Java StackTraces) via Logstash Filter Verifier?
@magnusbaeck 1. Is this currently possible? 2. Thanks for this great convenient tool.
