There is the test device that you can enable in /etc/sane.d/dll.conf. Just 
uncomment it. then you get two extra test devices.

There is also the pnm test backend, but that isn't necessarily even compiled 
for your distribution as it is seen as a potential security risk. with it you 
can specify a image that it returns in the scan. I think it requires a pnm 
image. I have not tried it for many years tho...
