What is design refactoring?

What is design refactoring?

Refactoring is a disciplined way to restructure code when small changes are made to the code to improve its design. An important aspect of a refactoring is that it improves the design while not changing the behavior of the design; a refactoring neither adds nor removes functionality.

What is the most common cause of refactoring problems?

The most common cause of refactoring problems is not in the code — it’s a lack of proper tools. Refactoring nearly always includes renaming variables and methods, changing method signatures, and moving things around. Trying to make all these changes by hand can easily lead to disaster.

How do you refactor a bad code?

Refactoring: Improving the Design of Existing Code….When I have to deal with adding functionality to bad code, my usual approach is:

1. Write automated tests for every important feature that must work (as most bad code doesn’t have any tests).
2. Do code changes.
3. Make sure the tests are still working.

What would not be considered refactoring?

Always to make it easier and safer to change in the future. Fixing any bugs that you find along the way is not refactoring. Tightening up error handling and adding defensive code is not refactoring. Making the code more testable is not refactoring – although this may happen as the result of refactoring.

Does refactoring improve performance?

2 Answers. A refactoring could indeed affect the performance, but not always in the ways that you expect. Martin Fowler gives a nice example in his book “Refactoring: improving the design of existing code”. In this example, separating one loop into two actually improved the performance.
