A Practical Guide to Testing in DevOps

About the Book

As organisations shift to a culture of intense collaboration and rapid delivery, the expectations on testers are changing. What does testing look like in an environment with automated build and deployment pipelines? How does appetite for risk change once a product can be tested in production? Who should testers look to connect with across the organisation and how can they work together effectively to deliver quality software?

This book offers direction and advice relevant to anyone involved in testing in a DevOps environment.

It might have “testing” in the title but this book is not just for testers, this is a must-read book for any team looking to adopt or improve their approach to DevOps! This book provides plenty of ideas, tips and advice. I particularly like the way the book explains pros and cons of different approaches, allowing readers to make up their own mind about what will work for them. I will be referencing this book a lot in future!

The book is really insightful and you will find a lot of practical descriptions in it along with the pros and cons, she has made sure that concepts and practices are understood with proper context. The best part of it are the experiences shared by practitioners and the examples curated from the industry. All in all, a highly recommended read!

First of its class. I love the way it's written in simple and plain language. Filled with nuggets of wisdom. Katrina's book consists of lots of practical advice and some great case studies. Throughout the book, Katrina remains close to the core idea. A must-read for people involved in software development.

It doesn’t matter if you’re currently working in a DevOps environment or not. If you’re involved in software development as a tester or any other role, Katrina’s new book is one to add to your library. It is thoroughly researched (links to other writings will keep me busy reading for months), and filled with many great examples. Just the “Rethinking the test pyramid” chapter alone had me quickly grabbing for my moleskine to jot down ideas! I highly recommend this book.

DevOps has a huge impact on testing, and testers. Based on her personal experience and extensive research, Katrina describes the changes that are required to test effectively in a DevOps environment. Amongst other things, DevOps teams are required to shift-left and shift-right testing, create an effective test strategy that minimises the impact on delivery times, and decide whether to test and monitor changes in production.

The material is easy to digest while still being chock full of quotes, research, and real industry examples that are easily referenced thanks to the clickable links in the e-book format. After reading this book, I feel like I have a good handle on what to expect as a tester as my responsibilities change in the DevOps shift.
