Test-Driven Development: A Practical Guide David Astels
Publisher: Prentice Hall PTR

As part of TDD (Test Driven Development) one should ideally write the tests first, and later write the code that makes the tests go through. I have a small issue with the base context class: In my opinion, it hurts readability. Want to understand the patterns involved in test-driven development. I'm hoping to follow a book that guides its readers through the agile process to develop a application using TDD. We're going to use this style on a new project so its great to see practical guides that you can point people at. Traditional TDD; Driving your tests from a domain/user story perspective rather than technical perspective. But not all is peachy - There is one methodology that I'm having only partial success in convincing my team that they should use – namely Test Driven Development (TDD). The first parts of the series are more theoretical, while as the last part will be fully practical, since we are going to implement some example code using TDD. Working with Legacy Code: Michael Feathers' book is the definitive guide to test-first development in scenarios where you are working with legacy code that has no tests. The practical “problem” with TDD is that unit tests are code calling code, and therefore for the unit tests to even compile, let alone run, you need the target code to be called within the unit tests to exist in some form. Above, I mentioned the social incentive built into making our tests results public, but the practical value is important, too. All this is changing, though, integration to keep us honest. When this was explained to a group of people that have never even used TDD, their heads nodded and I saw about 30 lightbulbs come on in the room. Those are the 'hard-to-test' areas, the things production code . We also have some key practices that guide our use of these tools. Yet, I believe that not so many developers (including myself) have really acknowledged the messages it conveys. Oh well, this book (Test-driven development: a practical guide by Dave Astels) is not so new. And more glaring than anything else: The dearth of great tools and established practices for automated testing has made the agile ideal of true test-driven development (TDD) hard to attain. I wanted to talk about the issues that people get when they begin working with TDD, the same issues that tend to make them abandon TDD after an initial experiment.
