Talk about in-the-wild testing! Pintester takes crafts, recipes and DIY projects found on Pinterest and tries her hand at actually making them in the real world.

This site makes an excellent case for testing with your end user. Just because it makes sense and is easy to you doesn’t mean it will translate well to the real world. Without usability testing, you may be missing intuitiveness or instructions without even knowing it. Here’s a prime example I dug up from Pintester:

Summertime Splashy Nails

[Official] Directions:
1. White Base Color
2. Place small dots of colored polish in corner of nail.
3. Spread colored polish dots outward with a toothpick.
4. Apply topcoat.
5. Voila!

I wasn’t sure if I should put all the dots in the corner of my nail at the same time, or dot and spread, then dot and spread. …

I tried variations on all the other fingers. Bigger dots. Smaller dots. Less toothpick pressure. Using my finger instead of a toothpick. Putting the dot in a different spot. All met with varying degrees of fail.

Keep up the hard work Pintester!
