We asked SitePoint authors what developer toys they would want for Christmas, then managed to source them — without relying on Santa.
When I started with Rails, I was introduced to something called “Test-Driven Development”. The theory is simple: write tests for your code, so that you can make changes to it with confidence.
Why I wanted this book
Initially, that sounded like a no-brainer, but when I tried putting it into practice I was assailed with questions and doubts: What do I test? Which tools should I use? Am I even doing it right?
Fast forward several years and the situation hasn’t become much better. Sure, I write tests for my code, but as my apps get more complex, the questions and doubts remain. That’s why “Rails 4 Test Prescriptions” by Noel Rappin was high on my Christmas wish list.
The experience so far
In summary, although rather dry in places, this book contains something for every Rails developer. Whether it’s getting up to speed with unfamiliar tools, focusing on what to test, or choosing the right tools for the job, this is a veritable must-have for your coding toolbox.
