Advanced Test Driven Development

Uncle Bob's Advanced TDD 

This two-day, hands on course will explain the principles of Test Driven Development as described in Agile Software Development: Principles, Patterns and Practices, by Uncle Bob.

This is an intense, exercise-driven course, written and delivered by Uncle Bob Martin, which focuses on the design of clean, robust, and maintainable unit and acceptance tests. You will learn the principles of test design, and the practices of keeping tests clean. More importantly, you will learn the principles of designing applications for testability. Exercises include the refactoring of bad tests, the writing of clean tests, and the design and refactoring of applications to make them testable.

Exercises are in Java, but are applicable to C#, C++, and other object oriented languages.
