Mocking File Endpoints in Camel

I wish to unit test a camel route that looks as follows:


I’ve replaced the from with a direct endpoint using adviceWith and have a producer template to send a test exchange, however the body of the In exchange in the configProcessor is of the type File and questions like Mocking Files in Java – Mock Contents – Mockito recommend against trying to mock File objects.

Is it possible to pass another object that extends File but doesn’t write to disk, or should I create a temporary file, or even refactor the configProcessor to split out the I/O from the processing?


In the end I chose to split out the processing by making it a separate function from process(). It’s not quite what I’d hoped for, but it works.
