NIFI-1376 Provide access to logged messages from TestRunner
Here is a possible mechanism to allow Processor unit tests to access and
verify messages written to the log. All fields passed to the logger are
available within the test: Marker, message/format, Throwable and any arguments.
Example usage:
final List<LogMessage> errorMessages =
runner.getLogger().getErrorMessages();
assertEquals("Expect a single ERROR level message", 1,
errorMessages.size());
assertEquals("{} Failed to convert {} from Avro to JSON due to {};
transferring to failure: {}",
runner.getLogger().getErrorMessages().get(0).getMsg());

> Project: Apache NiFi
> Issue Type: Improvement
> Affects Versions: 0.4.1
> Reporter: Richard Miskin
> Priority: Minor
>
> It would be useful to be able to verify the log messages raised by Processors
> and ControllerServices during tests.
> As an example use case, imagine a processor with multiple possible errors
> that should cause a flow file to be transferred to a failure Relationship,
> but different messages should be logged.
