Book Description

Ruby has built an enormous following of developers attracted by its intuitiveness, flexibility, and simplicity. Meanwhile, Microsoft’s .NET has grown and matured into a platform of unparalleled power. IronRuby brings them together, enabling developers to write elegant, efficient Ruby code that seamlessly integrates with .NET objects and leverages .NET’s full capabilities. Now, in IronRuby Unleashed, one of IronRuby’s most respected early adopters demonstrates how to write outstanding production software with the brand new IronRuby 1.0.

Writing for both Ruby and .NET developers, Shay Friedman covers every facet of IronRuby programming. Friedman begins by explaining how IronRuby leverages the new Dynamic Language Runtime (DLR) libraries to run atop the .NET Framework and access its resources. Next, he presents an in-depth IronRuby tutorial that ranges from basic syntax and object-oriented programming techniques through advanced concepts. Building on this foundation, you’ll learn how to make the most of a broad spectrum of .NET platform features.

IronRuby Unleashed thoroughly illuminates the use of IronRuby and .NET with today’s most powerful frameworks and technologies, including WPF, ASP.NET MVC, Ruby on Rails, and Silverlight. You’ll also find detailed coverage of unit testing, as well as cutting-edge techniques for extending IronRuby with C# or VB.NET. Download Now »

Book Description

Everyone in the Ruby world seems to be talking about metaprogramming–how you can use it to remove duplication in your code and write elegant, beautiful programs. Now you can get in on the action as well.

This book describes metaprogramming as an essential component of Ruby. Once you understand the principles of Ruby, including the object model, scopes, and eigenclasses, you’re on your way to applying metaprogramming both in your daily work and in your fun, after-hours projects.

Learning metaprogramming doesn’t have to be difficult or boring. By taking you on a Monday-through-Friday workweek adventure with a pair of programmers, Paolo Perrotta helps make mastering the art of metaprogramming both straightforward and entertaining.

The book is packed with:
* Pragmatic examples of metaprogramming in action, many of which come straight from popular libraries or frameworks, such as Rails.
* Programming challenges that let you experiment and play with some of the most fun, “out-there” metaprogramming concepts.
* Metaprogramming spells–34 practical recipes and idioms that you can study and apply right now, to write code that is sure to impress. Download Now »

Book Description

Automated testing moves much of the labor of testing off the developer and makes it easier as well as quicker to find bugs and fix them. Automated tests run faster, increase test coverage, and lower costs. However, testing is neither an easy process nor remotely exciting for most developers. But with the right techniques and tools, testing can become a simple and gratifying part of the development process.

With this helpful guide – from an expert – in your hand, testing will not be a tiresome topic for you anymore. You will learn how to test your Python projects in the easiest way, making other parts of the development process easier and more enjoyable.

This book covers the tools and techniques of automated testing and test-driven development. Starting from the very basics, the chapters introduce new tools and techniques in simple, accessible language with step-by-step examples. You will explore how to make testing easier and more accurate with Python’s doctest module and learn test-driven development using the unittest framework. You will also learn how to keep your units separate from each other and discover a simple and easy way to integrate Mocker and unittest. Next, we cover integration testing and web application testing.

Automated testing gives developers better feedback, faster and more often. Bugs get found sooner and fixed better, with less effort. By the end of this book, you will have all of the skills needed to benefit from automated testing.
