--verbose ?

The test resources are not packaged in the grd generated pak files. For the
tests, these will be still embedded in the binary. I am working on how to
migrate the test resources also out of the binary but that shouldn't stop us
from landing these changes.

To differentiate that, I used '--for-testing'. I think '--verbose' wouldn't
serve the purpose due to different literal meaning. WDYT?
