For any software developer who has spent days in “integration hell,” cobbling together myriad software components, Continuous Integration: Improving Software Quality and Reducing Risk illustrates how to transform integration from a necessary evil into an everyday part of the development process. The key, as the authors show, is to integrate regularly and often using continuous integration (CI) practices and techniques.

The authors first examine the concept of CI and its practices from the ground up and then move on to explore other effective processes performed by CI systems, such as database integration, testing, inspection, deployment, and feedback. Through more than forty CI-related practices using application examples in different languages, readers learn that CI leads to more rapid software development, produces deployable software at every step in the development lifecycle, and reduces the time between defect introduction and detection, saving time and lowering costs. With successful implementation of CI, developers reduce risks and repetitive manual processes, and teams receive better project visibility.

The book covers

How to make integration a “non-event” on your software development projects
How to reduce the amount of repetitive processes you perform when building your software
Practices and techniques for using CI effectively with your teams
Reducing the risks of late defect discovery, low-quality software, lack of visibility, and lack of deployable software
Assessments of different CI servers and related tools on the market

The book’s companion Web site, www.integratebutton.com, provides updates and code examples.

CUSTOMER REVIEWS (Average Customer Rating: 4.5 based on 14 reviews)

Fine for an introduction; otherwise of little help

If you have not been exposed to continuous build/integration, this book covers the approach along with the advantages and points you to some references.
However, if you already have an understanding of CI or have decided that you need to set up a CI environment, this book doesn't add much: few details, little discussion of fine points, etc. That is, don't buy this book if you want concrete help setting up CI.
There is quite a bit of repetition (how many times does one have to list the advantages of CI, or a dedicated build machine, or whatever?).
I found Ant in Action (Manning) much more useful: both in providing the motivation for CI, explaining fine points, providing examples, and in breadth (even if "Ant in Action" is nominally about a Java build tool).

Readable, well-organized, outstanding

As Martin Fowler says in his foreword to this book, all of this information is available on the internet. However, that should by no means demean the value of this book. This is an extremely readable and well-organized presentation of this important development practice. Often the organization and comprehensive analytical thought are themselves important contributions to a given topic, and that is what Duvall, et al deliver here. Highly recommended.

Good balance between concepts and practice

As a software developer, you know that one of the critical period in a project is when you try to make integrate your code in the overall application and push it towards the final user. It is sometimes a long process that you would like to accelerate so that you could obtain a quicker feedback on the quality of your code. This book written by Paul Duvall, with Steve Matyas and Andrew Glover, will help you improve the way you build and deliver software.

After a initial presentation of the continuous integration (CI) concepts and objectives, the content of the book goes far beyond the simple "continuous build" aspect to cover all disciplines concerned by CI: risk management, configuration management, database evolution, software testing, inspections, deployment. It is clear that CI is just not installing a suite of tools, but is mainly changing software development practices and process. Each chapter is well structured with practical examples related to real life situations. The book reach also nicely the objective of maintaining a balance between a somewhat tools- and language-neutral position, but still giving enough practical advice so that you could quickly adapt the advice to your own software development environment. Final appendixes give valuable information on CI resources and evaluating available CI tools.

Finally, you can get more and updated information on continuous integration and download book's chapter two from the Web site associated to the book: http://www.integratebutton.com

The Power of Feedback

This book is an excellent overview of why Continuous Integration is important and about more than just compiling frequently. The book helps you to understand why to do CI, what you can do beyond building, and how to do it. In addition to general principles, the book points you to some excellent tools and resources. This book is an excellent companion to Software Configuration Management Patterns: Effective Teamwork, Practical Integration; it provides teriffic information that support the build patterns in that book. You might already know some of the information in this book, but it is worth buying if you need to encourge CI in your organization for the clear discussion of why CI matters and the for the detailed advice on how to implement it.

An outstanding guide any serious software development library needs.

Any software developer who has spent days in 'integration hell' handling a complexity of software components will appreciate the invaluable information in CONTINUOUS INTEGRATION: IMPROVING SOFTWARE QUALITY AND REDUCING RISK. From the initial concept of CI and its practices to over forty CI-related practices from database integration to development, this book covers the entire cycle of CI development and surveys all kinds of events, repetitive processes, and more. An outstanding guide any serious software development library needs.
