The Modern QA Engineer Skillset

The course, in 26 books

Everything on this site is free and stays free — that doesn't change. The books are built on top of the free material: the same ground, expanded and edited, plus what was never on the site — worked examples, exercises, self-assessment quizzes, and the interview questions with answers. Books are sold on Leanpub and revised as the industry changes; buying once gets you every future update of that book.

Start reading now: the first chapter of every book is free in the online readerNew! — with interview drill mode and instant topic filters. Jump straight to the interview questions drill, or read all 26 books online with a subscription: $60/year.

The online reader for these books is built on Bookatlas, our open-source engine for turning markdown books into zoomable tile atlases.
