What tools to use for UX analysis and testing?

Question

Layouts and prototypes

I design interfaces for websites and applications.
I have always focused on the UI.
But now I want to get as much knowledge as possible about UX research, analysis and testing.
Where to start, what to read for this? What tools are most popular for such analysis?

Answer 1

Good books on UX design, you can also get a lot of interesting testing tools from there.
New directions in computer systems design - Jeff Raskin
Mental hospital in the hands of patients - Alan cooper
Interface. Interaction Design Fundamentals - Alan Cooper
Don't Make Me Think - Alan Cooper
A Good Interface Is an Invisible Interface
Design of Common Things - Donald Norman
Don't look at the fact that the books are old. Now the same logic is used to a greater extent, and the same tools.
