The 3 Types of Unit Test in TDD

Test Driven Development (TDD) and Unit Testing aren't necessarily the same thing, but they both produce unit tests. In either case there are only really three unit test types.

In this episode, Dave Farley, author of "Continuous Delivery" and "Modern Software Engineering" explores some of the nuts and bolts of TDD and how to put it to use in your software engineering approach. This TDD tutorial explores the three types of test with some simple examples to demonstrate each one. It then goes on to explore the difference between stubs, fakes, spies and mocks in testing and describe some common difficulties that people sometimes face.
