An incremental zone transfer won't transfer the .ixfr file.  The .ixfr
file is just a log of the changes made to the zone and which serial
number changes they correspond to.  A slave requesting an incremental
zone transfer will receive those changes and will apply them to its
copy of the zone, but won't necessarily create a .ixfr file.

Also, as "DNS and BIND" says, if you use IXFR, you can't manually edit
zone data files.  So your testing won't work anyway.
