[logback-user] How should I unit test my programmatic setup of appenders?

I want to unit test some methods I have for programmatically adding appenders to the root logger. It seems that I don't have full access to the things I have set, specifically the marker evaluator. Additionally, as the markerEvaluator is not a filter, I can't call the getFilterChainDecision method. Is there a better approach to doing this? I've seen posted the idea of using a ListLogger to perform logging and then query to see if the correct logs went through, but that doesn't test "my" appender.
