bash: stop a for loop if the internal command exits with non-zero code

Question

I have this code:

for x in 1 2 3;
do
  ./test.sh $x
done

test.sh looks like this

echo "$1"
if [ "$1" = "2" ]
then
  exit 1
else
  exit 0
fi

how do I get it to output only

1
2

Instead of

1
2
3

break if the test.sh fails:

for x in 1 2 3;
do
  ./test.sh $x || break
done
