In this interview from QCon London 2008, Erich Gamma discusses the Jazz project, why Eclipse has been successful, the strict Eclipse release schedule, JUnit, Design Patterns, how to identify a design pattern, design patterns and the 'Don't Repeat Yourself' principle, the design pattern community, and whether dependency injection is a design pattern.
Kent Beck, renowned co-father of XP, TDD, and JUnit itself, tells a story about tracking down a defect in a new JUnit feature, JUnitMax, with unit tests instead of a debugger. He explains a method shown to him by current JUnit lead developer, David Saff, where a high level unit test is recursively inlined until a super concise test is created down at the very root of the defect.
The recent release of Clover 2.4 highlights a new "Test Optimization" feature that offers to speed up CI builds and allow developers to spend less time waiting for their tests to run. The feature leverages "per-test" coverage data to selectively run only the tests impacted by your code changes.
In this interview with Eli Lopian of Typemock, he discusses the impetus for Typemock, it's differentiators and program futures. Typemock was originally created to fill a need for a Test Driven Development tool within the .NET community.
Recently published, Infoq was able to speak with all four authors about their personal views on Model Based Testing: Jonathan Jacky, Margus Veanes, Colin Campbell and Wolfram Schulte. Also included is a chapter excerpt with thanks to Cambridge University Press.
In this interview made during Agile 2007, Dr. Hakan Erdogmus, Editor in Chief of IEEE Software, discusses about TDD starting from a study done by Ron Jeffries and Grigori Melnik and published as "TDD--The Art of Fearless Programming" in the IEEE Software magazine. Hakan talks about current misunderstandings regarding TDD's role in software development and the adoption issues it faces.
In this interview from QCon San Francisco 2007, Cédric Beust discusses designing and architecting for testability, problems that hinder testability, test-driven development, the "Next Generation Testing" book, performance testing recipes, and testing small, medium and large codebases.
Writing a test makes you clarify your ideas about what needs to be done, and making the test pass means that you know that you've added a little more functionality today. Having a comprehensive suite of tests gives you the confidence to get on with things because you can tell when you've broken the system, and tests that are difficult to write show you where you need to improve.
In this presentation from QCon San Francisco, Cedric Beust and Alexandru Popescu discuss interesting features of TestNG such as grouping of tests, data providers for tests and dependency handling in tests, tips for designing easily testable code such as eliminating statics, extreme encapsulation and TDD, the importance of functional versus unit testing, and migrating from JUnit to TestNG.
This book guides the reader on crafting their own agile adoption strategy focused on their business values and environment. This strategy is then directly tied to patterns of agile practice adoption that describe how many teams have successfully (and unsuccessfully) adopted them. Business values are also a component of these patterns so your adoption is always focused on addressing your particular environment.
