Oops. You're right. I did have
Test::Warn::import.
I fixed this typo, but all the same, I get the same error as before and the test script dies.
$ perl t/01-test_errors.t
1..43
$@:
ARRAY(0x6acb08) is not a hash reference.
ok 1 - non-hash reference to cpf2data()
Can't call method "warning_like" without a package or object reference at t/01-test_errors.t line 18.
# Looks like you planned 43 tests but only ran 1.
# Looks like your test died just after 1.
Here,
ARRAY... is the warning that I want to trap.
