Test-Driven Development (TDD) is possibly the most effective single technique for improving the quality of applications under development. Yet many teams are either struggling to make successful TDD a reality or have failed to adopt it at all. A common reason for this is simply the ‘challenge of the unknown’ for a team adopting a new process and a new toolset at the same time, when they may have little or no experience of either.

We created ‘Testify’ to solve the problem of overcoming the technical barriers to TDD adoption. It was initially a thought experiment to see how far one could go in creating a self-contained TDD process, even before there is any functionality to test. It has since been developed to become a genuinely useful tool that has been used to start many new Test-Driven C#.NET projects.

Built upon a best-of-breed open-source tool stack, the Testify wizard allows you to create a new project complete with file structure, skeleton code, running unit tests, acceptance tests, code coverage measures and automated one-button build-and-test process. All it requires is a project name, and the rest is handled by Testify.

Introducing this demonstration, we outline the technical challenges and other reasons why many teams find adopting TDD difficult, and briefly present a set of principles for successful TDD. The rest is a demonstration of the Testify tool, its architecture and how you can use it to introduce TDD on your own project.
