Rails Test Prescriptions is a comprehensive guide to testing Rails applications, covering Test-Driven Development from both a theoretical perspective (why to test) and from a practical perspective (how to test effectively). It covers the core Rails testing tools and procedures for Rails 2 and Rails 3, and introduces popular add-ons, including Cucumber, Shoulda, Machinist, Mocha, and Rcov.Your Ruby on Rails application is sick. It's got bugs. Nobody remembers what that tricky piece of code was supposed to do, and nobody can tell what it actually does. Deadlines are looming, but every time you make the slightest change to the code, something else breaks.You need Test-Driven Development (TDD), a proven process for improving the design, maintainability, and long-term viability of software. In TDD, the tests come first, and then code is written to match the expectation of the test. Using TDD means writing better code faster.Ruby on Rails has unparalleled support for TDD. In addition to the tools that Rails has built-in, a large and thriving testing community adds new tools at an accelerating rate. Rails Test Prescriptions is your guide to the entire Rails testing ecosystem.Containing both practical code examples and discussion of why testing works, this book starts with the most basic features delivered as part of core Ruby on Rails. Once you've integrated those features into your coding practice, you'll want to use popular third-party testing tools such as RSpec, Shoulda, Cucumber, Factory Girl, and Rcov. Rails Test Prescriptions will show you how to use these tools and when they are appropriate. Rails Test Prescriptions will cover both the current Rails 2.3.x version as well as the initial 3.0 release.If you are a Rails programmer who tests code, this book is an invaluable guide to the latest in available testing tools. If you are a Rails programmer who doesn't test code, then start testing immediately: this book can help.

The advantage of using Rails is its agility; it makes developing your web applications easy and fast. The disadvantage is that it can leave holes in your security if you are not aware of common vulnerabilities. It's a nerve-wracking and unfortunate fact that there are plenty of malicious people lurking on the Web. As a Rails developer, it is essential that you understand how to assess risk and protect your data and your users.Security on Rails uses established security principles to teach you how to write more secure software, defend your applications from common threats, and encrypt your data. We'll give you an example of a hacking exploit, and explore how to fix the weaknesses in an application.You'll learn the steps you need to take to control access to information and authenticate users, including cryptography concepts and authorization. In addition, you'll see how to integrate your applications with external management systems; in short, the crucial details you must consider to protect yourself and your data.The most important element of security is to plan for it before it becomes an issue. Security on Rails helps beginner and intermediate developers to take control of their applications and guard against attacks.
