With help from
CAMEL-8656 we can enable unit tests to generate xml files with route statistics.
What we need is then a mvn plugin to generate a nice report from those, such as a html page that has a summary, and then a detailed route with colored lines for route usage, so you can spot which routes has unused parts etc.
For starters the route can be dumped as xml from the report as its already in xml format. Its a matter of removing the noise, and then apply css or what style to do if exchangesTotal=0 and if its > 0 etc.
