Refactoring journey

Lazy you will be-> use your IDE

Don’t forget the Golden Rule

We will refactor code : Improve the Design of existing code.
The approach (Kent Beck wisdom) :

1. First, make the change easy (refactor)
2. Then, make the easy change

Before any changes :

• Check the tests
• Make sure they are all Green

I strongly advise to use the Split Feature of your IDE to organize your work
