Jython is an open source implementation of the high-level, dynamic, object-oriented scripting language Python seamlessly integrated with the Java platform. The predecessor to Jython, JPython, is certified as 100% Pure Java. Jython is freely available for both commercial and noncommercial use and is distributed with source code. Jython is complementary to Java.
The Definitive Guide to Jython, written by the official Jython team leads, covers the latest Jython 2.5 (or 2.5.x) from the basics to the advanced features. This book begins with a brief introduction to the language and then journeys through Jython’s different features and uses.
The Definitive Guide to Jython is organized for beginners as well as advanced users of the language. The book provides a general overview of the Jython language itself, but it also includes intermediate and advanced topics regarding database, web, and GUI applications; Web services/SOA; and integration, concurrency, and parallelism, to name a few.
What you’ll learn
* How to handle Jython basics like language syntax and concepts
* How to use the Jython scripting language for I/O, Java/Jython integration, and Jython in an IDE and databases [click to continue…]

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.
Whether you’re a Ruby apprentice on the path to mastering the language or a Ruby wiz in search of new tips, this book is for you. [click to continue…]

Product 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. [click to continue…]
