Can refactoring and unit testing really create robust “working software” that survives the real world? In this story adapted from his book Release It! Michael Nygard contends that "abstractions leak": we need to attend to architecture, even in Agile projects, to guard ourselves against the 5AM failures that occur when foundational abstractions misbehave.
There are many occasions where software creates XML output: XML documents are used for data interchange between different applications, web application create (X)HTML output or respond to AJAX requests with XML, and this has to be tested as much as anything else. In this article, Stefan Bodewig explains how to perform those tests with the XMLUnit framework he has co-authored.
Dan Bunea shows developers how TDD can be applied in .NET using Selenium RC and Castle. Test first principals provide architects a way to quickly jump into active development early in the application development lifecycle. The benefits of TDD are a drastic reduction in defects as well as increased flexibility in the code base since the application evolves quickly through an iterative process.
