Blog posts and books can make refactoring look easy. "Here's the synthetic example, now use X scripted transformation." Unfortunately, codebases in the wild do not come with the right refactoring patterns hyperlinked.

In this course you be introduced to techniques and tools to help you decide where to begin refactoring in a large, legacy codebase. You will practice moving those first shovel-fulls of code without triggering an avalanche of test failures.

We will practice identifying issues, explore strategies to attack them, and put them into practice. This is not a walk-through of every refactoring in the cannon; this is practical application of great techniques

What You’ll Learn

In this online course you will refactor real production code that is ripe with code smells, tight coupling, leaky encapsulation, and missing abstractions.

  • Getting Started: How to explore a large code base
  • Design: Practice identifying refactoring targets
  • Testing: How to ensure that your tests have your back
  • Refactoring: How to safely reshape your application using step-by-step transformations

What’s In a Class?

This is not “sit back and watch slides” — all Jumpstart Lab courses are hands-on. We work with real applications and you’ll implement these tools and techniques yourself. By the end of the class, you’ll have real experience, real skills, and real code to reference.

Who’s this for?

This course is built for experienced developers who feel comfortable with Ruby and Rails.

What equipment is needed?

For this session you'll need:

  • a computer with Mac, Linux or Windows
  • Ruby 2.0 and Rails 3.2 and 4.0 installed
  • The join.me local client installed
