Although, the comment block just above test_seq() in
test-lib-functions.sh says otherwise:
Print a sequence of numbers or letters in increasing order. This
is similar to GNU seq(1), but the latter might not be available
everywhere (and does not do letters). It may be used like:
for i in $(test_seq 100)
do
for j in $(test_seq 10 20)
do
for k in $(test_seq a z)
do
echo $i-$j-$k
done
done
done
