Reddit mentions of Software Testing: Fundamental Principles and Essential Knowledge

For a book that provides both a good introduction to testing terminology and concepts, as well as a fair amount of practical/instructional examples, I really like Software Testing: Fundamental Principles and Essential Knowledge. Also, I'm not sure whether you're wondering about getting started doing QA for your own games, or getting a job at a game company. If the latter, I'd say that the best way to get started depends on what your goals are:

• If your ultimate goal is to move into a different type of role within the game industry, simply being in the right place at the right time (i.e., an area that has at least a few game companies, during the time when people are hiring testers to get their games in shape for pre-holiday ship dates) and demonstrating that you are a mature and dependable person with good computer skills and a knowledge of basic testing principles may be sufficient. While you're working in an entry-level test role, keep on improving the relevant skills for the type of job you hope to eventually have, and then apply for one of those openings within the company when you're ready. Caveat: this is much more likely to happen at a small to medium-sized game company than at one of the major ones, where entry-level testers are often segregated completely from any development, art, or production people. At small companies, though, I've seen numerous instances of people who started off in manual tester positions while they were in college or otherwise improving their skills eventually move up into art or coding roles.
  
  
• If your eventual goal is to end up at a higher-level testing role within the game industry-- SDET, QA Manager/Lead, etc.-- one thing that can help is starting your career outside of games. My first job out of college was at a company that made medical software; I was able to get some real-world coding, testing, and planning experience, and then managed to skip the entry-level game testing jobs and move directly into higher-level test roles. A lot of other SDETs I've worked with in games have had a similar career path, and I've seen a lot of people with an eventual desire to be SDETs or leads get stuck in more entry-level testing roles when a black box game testing job was their first role within the game industry. I'm not quite sure why this is the case, but this is definitely something I've observed.
  
  Sorry for the tl;dr, and I hope this helps! If you have any questions about things like finding and applying for QA jobs, I'd be more than happy to answer them.
