Stub Component
The stub: component provides a simple way to stub out any physical endpoints for easy testing. Just add stub: in front of any endpoint URI and things just work.
Under the covers the Stub component creates VM endpoints.
So if you are in development and want to try a route out but don't want to connect to a specific Smtp or Http endpoint, just put stub: in front and stub it out!
URI format
stub:someUri
Where someUri
can be any URI at all with any query
