Because the ok/not ok protocol is simple, we could do it by hand:
$count++; print $rocket->warmup ? "ok" : "not ok", "$count\n";
$count++; print $baby->sedated() ? "ok" : "not ok", "$count\n";
But Test::Simple makes it easier:
use Test::Simple tests => 2;
ok($rocket->warmup, 'rocket warmed up');
ok($baby->sedated(), 'baby sleeping like ... well ... a baby');
This will print out:
1..2
ok 1 - rocket warmed up
not ok 2 - baby sleeping like ... well ... a baby
In fact we can get even easier with no_plan:
use Test::Simple 'no_plan';
ok($rocket->warmup, 'rocket warmed up');
ok($baby->sedated(), 'baby sleeping like ... well ... a baby');
