For the record, I was able to make the test pass by rewriting it as
follows:

fun! Test_FOO_dup_completion()
new
imap <buffer> <expr> <silent> <plug>(Dup) <sid>dup_complete()
call feedkeys("ajump", "tx")
call feedkeys("a", "t!")
call feedkeys("\<plug>(Dup)", "tx")
call assert_equal("jumpjump", getline(1))
bwipe!
endf

Life.
