When I am away from my scanner and want to hack (and indeed for things 
like unit tests), I use the "test" backend.

It is not exactly the same as a fujitsu scanner, but for most frontend 
development, I find it very useful.

I would also recommend using the C, Python, or Perl APIs for libsane 
rather than wrapping scanimage.
