The correctness of the actually written data is already checked in
`checkTransferredContents`. I do not see what you win by replacing
`ByteArrayInputStream` by `FileInputStream`. What additional risks do you
cover, and what is so special about `FileInputStream` compared to any other
`InputStream`? `FileInputStream::transferTo` is already checked by its own unit
test.
