Cutting Code Quickly: From 0% to Cleanly Refactored 100% Tested Code

A talk by Llewellyn Falco Creator, ApprovalTests

In this guided demo, we are going to look at 3 different techniques that are remarkably powerful in combination to cut through legacy code without having to go through the bother of reading or understanding it.

The techniques are:

Combination Testing: to get 100% test coverage quickly

Code Coverage as guidance: to help us make decisions about inputs and deletion

Provable Refactorings: to help us change code without having to worry about it.

In combination, these 3 techniques can quickly make impossible tasks trivial.

Will will be doing this on the Gilded Rose Kata,

It is extra beneficial if you try it out yourself first so you can see how your implementation would differ.
