From programmers to testers - what literature is worth studying?

Question

Software testing

It turned out that instead of a programmer, he became a tester (and this suits me perfectly). Perhaps in my case there is some more "specialized" literature? Or just google books for testers?

Answer 1

I recommend Copeland to start with. An excellent author, moreover, the ISTQB testing certification system is also built on it.
You can certainly read the same Savin.

Answer 2

I personally recommend Kulikov - well systematized and relevant. From the English-language materials of Rex Black.
