Branching by abstraction

When branching by abstraction, you are not keeping two versions of your code side by side using branches, but you keep them side by side in your code base. For example, when you want to change the implementation of a class called FoodClassifier, which implements the IFoodClassifier interface, you go through the following steps:

1. You refactor the name of the FoodClassifier class to FoodClassifierToBeRemoved.
2. You create a copy of the complete FoodClassifierToBeRemoved class.
3. You name this copy back to FoodClassifier.

At this point, your changes should look like this:

public class FoodClassifier : IFoodClassifier{ public FoodClassification Classify(Food food) { // Unchanged classification algorithm } }public class FoodClassifierToBeRemoved ...
