How the users interact with your prototype is ultimately the most important test. Bring your prototype to users, have them interact with it, and see what is and isn't intuitive about your solution.

HOW TO MAKE THE MOST
OUT OF FEEDBACK.
Friends and family care about you. They want to encourage you and spare your feelings. Testing on stranger will yield much more blunt and useful feedback.
Listen to your user! Defending your idea is counterproductive.
Your role is to use empathy and learn- keep asking "why" and listening, rather than talking at them.
Once you have feedback, modify your prototype and test it again.
The more rounds of remodeling and testing you go through, the better you will hone in what your target consumer really needs.
SOME FINAL NOTES
THANKS FOR STICKING AROUND FOR THIS LONG!
HERE ARE A FEW THINGS TO KEEP IN MIND BEFORE YOU LEAVE.
IF YOU'RE LINEAR...
You're doing it wrong!
If you get stuck, don't be afraid to go backward.
Say you test your prototype, and your user is not at all interested in the solution. Hm. After all that work!
Use empathy- get really detailed feedback from your tester. Maybe they will say something that causes you to redefine the problem. Or, they'll remind you of an old idea from the ideate stage, and decide to pursue that idea instead.
Design Thinking isn't just for Entrepreneurs
At its core, Design Thinking is a human-centered process for problem-solving. You can apply it to your own day to day problems. Remember this toolkit whenever you get stuck.
