This is very close to what you call usability testing in the field of UX design.

The Nielson Norman Group has a good introduction to this: https://www.nngroup.com/articles/usability-testing-101/

Is this interesting to people on HN?

I majored in a mix between coding and design.

I think I read somewhere (and in any case it matches my experience) that the first user will catch 50% of the problems and that with 5 users you can catch close to 90%. So human testing is not just invaluable, it's pretty cheap for the benefits it brings.
