How to do Usability tests?

Question

Layouts and prototypes

I have been working with interfaces for a long time.
But that's it with testing and research of the target group did not work.
Tell me where to start? Tools or approaches?
Unfortunately, there is no time for huge books, at one time I re-read their wagon and a small cart.
I would like to have as much practice as possible.
