Refactoring Legacy Code  

Legacy code can be a beast: fragile, complex, and often lacking the necessary tests to ensure changes don’t introduce defects. But fear not! There are techniques you can use to effectively work with and extend it in a safe and effective manner.

We will delve into:

• Managing and improving legacy code
• Utilizing Test-Driven Development (TDD) effectively
• Applying the Strangler Fig Pattern to incrementally refactor code without breaking existing functionality

Learning Outcomes  

• Understand the concepts of the Strangler Fig Pattern
• Use Interfaces and Dependency Injection to isolate legacy code to be changed
• Learn the benefits for using the Strangler Fig Pattern as opposed to an application rewrite
