title: Change log4j settings in Camel TestSupport
body: <p>I am debugging some jUnit tests that use the Camel TestSupport interface. This gives me access to a log4j log but I can't seem to figure out how to get a reconfigured version of that. I want to be able to change the log level since a lot of my logs are written in a trace level instead of just info or debug.</p>
  
  <p>What is the best way to reconfigure this log's console output?</p>
  
  <p>Thanks</p>
