Because they are often large and complex, GUI programming tool kits can be hard to use. wxPython is a combination of the Python programming language and the wxWidgets toolkit, which allows programmers to create programs with a robust, highly functional graphical user interface, simply and easily. wxPython combines the power of an exceptionally complete user interface toolkit with an exceptionally flexible programming language. The result is a toolkit that is unique in the ease with which complex applications can be built and maintained.""wxPython in Action"" is a complete guide to the wxPython toolkit, containing a tutorial for getting started, a guide to best practices, and a reference to wxPython's extensive widget set. After an easy introduction to wxPython concepts and programming practices, the book takes an in-depth tour of when and how to use the bountiful collection of widgets offered by wxPython. All features are illustrated with useful code examples and reference tables are included for handy lookup of an object's properties, methods, and events. The book enables developers to learn wxPython quickly and remains a valuable resource for futurework.

This comprehensive guide to testing Rails applications delves into Test-Driven Development (TDD) from both theoretical and practical perspectives. It addresses core Rails testing tools and procedures for Rails 2 and 3, while also introducing popular add-ons like Cucumber, Shoulda, Machinist, Mocha, and Rcov. If your Ruby on Rails application is plagued by bugs and unclear code, TDD can help. This proven process emphasizes writing tests first, leading to improved design, maintainability, and faster development of better code. Rails offers exceptional support for TDD, complemented by a vibrant community that continually develops new testing tools. The guide features practical code examples alongside discussions on the efficacy of testing. It begins with the essential features of core Ruby on Rails and progresses to third-party testing tools such as RSpec, Shoulda, Cucumber, Factory Girl, and Rcov, explaining their usage and appropriate contexts. Covering both Rails 2.3.x and the initial 3.0 release, this resource is invaluable for Rails programmers who test their code. For those who don’t yet test, it serves as a crucial starting point to integrate testing into their development practices.
