Course details

Refactoring code is a key responsibility of software developers. It helps you develop quality code—the foundation you need to react quickly to change, add new features, and ship high-performance products. This course teaches the basics of refactoring, tailored for agile development. Instructor Richard Kasperowski helps you set up a test-driven development environment and walks through basic refactoring techniques: the rename variable, extract, and inline methods. In chapter two, he explains how to stabilize legacy code with outstanding technical debt—inefficiencies and errors introduced as the result of careless programming. Then he uses refactoring to simplify code, remove duplication, and build more reusable objects. Finally, he shows how refactoring complements an agile workflow, by demonstrating how to quickly add a new feature to the simplified codebase.

    The 2nd and 3rd paths of course are really interesting. I've known about an approach of working with legacy code.

    This course uses set of java code examples and goes into much details while explaining the concepts along the way. Problem with this approach is for someone not knowing much of java, it creates hindrance as we cannot relate to some parts. I was able to follow some concepts but overall I am not sure how I will be using these concepts fully on the projects and tech(mostly ETL) I work on. If you are into java development, then this should not be an issue for you. The course spends more time on the code than on explaining the theory behind.

    Excellent intro to Test Driven Development and how to apply it for both new code and the much more daunting task of refactoring legacy code. Highly recommended for any software engineering professional looking to improve their skillset, reduce their bug count, and/or confidently enhance code that they have inherited. The concept of pin-down tests is a critical concept that is explained and demonstrated extremely well. Essentially, before refactoring legacy code, you should create unit tests that confirm the existing behavior/functionality. Includes a great breakdown on how to use code coverage tools to identify missing unit tests, with real example of how to debug and address gaps in 'Branch coverage'. Great Stuff!
