Test-Driven Development
Test-Driven Development (TDD) is a practice for efficiently evolving useful code. While its name implies that it's mostly
about testing, test-driven development is primarily about design: it keeps programmers focused on exactly what they need to
build and helps them avoid over-engineering. Using this technique, programmers write a failing test, write code to pass the
test, refactor the code and... Read more |

Code Smells
Code smells identify common design problems in object-oriented code. This interactive lecture provides a good overview of
code smells defined by Martin Fowler & Kent Beck in their book "Refactoring: Improving the Design of Existing Code." In addition,
you'll learn about some new smells that have been categorized by Joshua Kerievsky and his colleagues.

The Refactoring Challenge
The best way to improve your refactoring skills is to practice cleaning up poorly designed code. And we've got just the thing:
code we custom-designed to reek of over 90% of the code smells identified in the refactoring literature. This poorly designed
code functions correctly, which you can verify by running a full suite of tests against it. Your challenge is to identify
the smells in this code,... Read more |

Mock Objects
When writing test and production code, it's useful to know when to introduce Mock Objects. This activity will help you understand
what Mock Objects are, how they function at runtime, common implementation variations and usage patterns.

challenge
To fully understand mock objects, you need to get your hands dirty. In this challenge, you'll be... Read more |

Evolutionary Design
How does nature evolve organisms and what does that have to do with software
development? If you study nature's approach to engineering, you often find that
highly sophisticated organisms evolve from simple beginnings. For example,
during the earliest growth stages, internal organs are basic but functional and will
mature over time.

challenge
After reviewing a description of a sophisticated software system, participants must decide what... Read more |

Refactoring War
What's the fastest way to learn Martin Fowler's classic catalog of 74 foundational refactorings? It's called "Refactoring
War," an educational game we invented to help groups rapidly learn a large number of refactorings. The game is played in teams
and involves viewing refactoring cards, comparing the usefulness of the cards and deciding on which card is most useful. The
team with the most... Read more |

Testing & Refactoring Adoption
The workshop coaches engage participants in a dialogue on adopting Testing & Refactoring in their workplace, including the
following questions: What technical practices will be most difficult to accomplish at our company? How will we test or refactor
specific code? Should we test or refactor our legacy code? What is the best way to transition to these new practices? How
will our new practices... Read more |

Unit Testing Legacy Code
To refactor legacy code, you need good unit tests. To write good unit tests, you need to refactor your legacy code. How do
you get out of such a mess? First, you isolate what it is you would like to unit test and refactor. Next, you use whatever
language is simplest to produce coarse-grained tests for that area of code. Once you've written enough of the coarse-grained
tests, you'll be able to... Read more |

We'll begin by telling some war stories of how we've unit tested legacy code (for example, C++ COM... Read more |
