Since this patch is touching only t5319, a more typical title would be:

And, since the title now mentions t5319, this can become simply:

Should this test_when_finished() have been added in an earlier patch?
It seems out of place here.

Alternately:
{
test-tool genrandom "bar" 200 &&
test-tool genrandom "baz $iii" 50
} >wide_delta_$iii &&
which makes it easier to see at a glance that both commands are
populating the same file. Same comment for the other files. (Not worth
a re-roll.)

Or, just use POSIX arithmetic expansion:
$(( $i + 1 ))

Ditto, POSIX arithmetic expansion:
i=$(( $i + 1 ))
(Not worth a re-roll.)

Perhaps indent the content of the {...} block?

It's odd to see all these tests ending by creating an 'expect' file
but not actually doing anything with that file.

There seems to be a fair bit of duplication in these tests which
create objects. Is it possible to factor out some of this code into a
shell function?
