Book Description

3 Feb 2013 1449323391 978-1449323394 1

One skill that’s essential for any professional JavaScript developer is the ability to write testable code. This book shows you what writing and maintaining testable JavaScript for the client- or server-side actually entails, whether you’re creating a new application or rewriting legacy code.

From methods to reduce code complexity to unit testing, code coverage, debugging, and automation, you’ll learn a holistic approach for writing JavaScript code that you and your colleagues can easily fix and maintain going forward. Testing JavaScript code is complicated. This book helps experienced JavaScript developers simply the process considerably.

  • Get an overview of Agile, test-driven development, and behavior-driven development
  • Use patterns from static languages and standards-based JavaScript to reduce code complexity
  • Learn the advantages of event-based architectures, including modularity, loose coupling, and reusability
  • Explore tools for writing and running unit tests at the functional and application level
  • Generate code coverage to measure the scope and effectiveness of your tests
  • Conduct integration, performance, and load testing, using Selenium or CasperJS
  • Use tools for in-browser, Node.js, mobile, and production debugging
  • Understand what, when, and how to automate your development processes

2.0 out of 5 stars Covers a wide range of topics with little depth 24 Feb 2014
By noob1211 - Published on Amazon.com
Format:Paperback|Verified Purchase
Please don't waste you're money on this book. It really isn't worth your time. Sure the author has a great index of topics, just take a glimpse of the topics in the index. One would expect a book to be worthy of a read, but it was an entire let down. The author does a horrible job explaining how to write good unit tests. And one of the examples he gives isn't even practical(i.e. add(a,b))...come on...! What a waste of time, and energy. I've rated this book 2 stars because you can find better material online for free about the same topics. This book should be called, "Tips for Testable Javascript"...because thats all it is....

5.0 out of 5 stars Very Helpful 6 Mar 2013
By J. Meador - Published on Amazon.com
Format:Paperback
This book really helped me understand the link between my code and testing it. It has lots of good examples, especially about code coverage, that I was able to use when testing my app. The 'Automation' chapter did a good job of pulling it all together even though I don't use Hudson I was still able to use most of the tips to automate my tests during builds. The book was also very informative in showing how to keep the code simple,i.e. single function, single value, and integrating the development and test activities into an Agile environment.
I would have liked to read more about testable patterns but the book did a good job of going over all the basics (& some not-so basics). Definitely recommended for JS developers and anyone else who tests JS.

2.0 out of 5 stars Not for pros; not for beginners 28 April 2014

You can learn anything in this book from a simple Google search. It is a duplicate information. Don't read this.

4.0 out of 5 stars great Book 11 Mar 2013
By yoni felberg - Published on Amazon.com
Format:Paperback|Verified Purchase
i like it because it takes the approach of how to write your code so it can be tested easy and not just
how to write tests.
i just hoped it had more complex examples like handling tests in specific javascript patterns like modules and others.
but it is a valuable book any way......
4.0 out of 5 stars Lots of good information, not well written 2 May 2014
By Ash - Published on Amazon.com
Format:Paperback|Verified Purchase
There is a lot in this book, but sifting through it to extract the useful information from the somewhat poor writing style is a tedious exercise. I give this 4 stars just because of the amount of resources it has pointed me to.
