Ah - so it's actually something ruby does, and not the mock library.
I hadn't realized that.
I'm not sure this is the best idea, but we could actually remove the
warning:
def execute_silently(&blk)
old_warning_level = $VERBOSE
$VERBOSE = nil
yield
$VERBOSE = old_warning_level
end
(or I could do this myself, in my own specs)
