Figure skating test session?
I don’t think you’ll fail. You’ll probably get a deduction though. Just calm down. You know your program. Take deep breaths and you can do this! 👍
You most likely won't fail on the spot. The judges will not ignore it, though- you'll get major points off of your element scores. When you do your half flip, focus on your half flip and that jump only. Think about that and disregard the salchow altogether for the time being. You just have to not let your nerves get the best of you and you'll do great!
