A Practical Guide to Testing in DevOps
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.
Reader Testimonials

Lisa Crispin
Tester, Author & Coach, USA
This book is going to be open on my laptop at all times going forward. I’m experiencing the challenges of testing with my team moving towards continuous delivery. And here is the book to help me with those challenges! This book guides us into the future of software testing and delivery. From continuous delivery, to the use of machine learning and artificial intelligence for testing, and beyond, the practices and examples in this book will lead us into the future of software testing.

Angie Jones
Senior Automation Engineer (SDET), USA
Great collection of research across many different companies curated and analyzed by the brilliant Katrina Clokie. What's great about this book is the attention to practicality. I highly recommend this as a comprehensive guide to devops for anyone involved in software delivery but especially testers.

Bas Dijkstra
Consultant, Netherlands
Whether you're looking for tips on how to thrive as a tester in a DevOps environment, or you're looking for ways to adapt your testing strategy to the current world of shorter delivery deadlines, Katrina's book will provide you with lots of useful advice, exercises and experience reports, not only from her own work experience, but also from other people and organizations that have been through it all. A highly recommended read.

Matthew Bretten
Test Engineering Lead, UK
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!

Faiza Yousuf
Consultant, Pakistan
I am going to add this book as a reference read for our SQA and SPM undergrad classes. 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!

Atulya Krishna Mishra
Scrum Master, India
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.

Teri Charles
Senior Software Tester, USA
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.

Nigel Charman
National Service Owner DevOps, New Zealand
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.

Jasmin Smith
QA Lead, USA
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.

David Corrales
Developer / QA Consultant, Ecuador
Chock full of techniques, insights and experience reports! Katrina's book holds knowledge for everyone that may be interested in how a DevOps environment could tackle its testing strategy. Highly recommended whether you have just heard of DevOps or are seasoned in its best practices.
