Thank you.

I already have use_ok in a test of its own so I don't need it here and will remove it.

Off to look at is now :)

UPDATE...it works...
Thanks choroba - it now works :)

I changed:
ok( $comp_pass1 == 1, 'compare 1' ); to is $comp_pass1, 1, 'compare 1';
use_ok to a simple use AI::Embedding; and
done_testing(10); and all(!) tests now pass :)
