Module Overview

Last week was devoted to the Data Design Recipe, which was the first step of the Function Design Recipe. This week we will cover the remainder of the Function Design Recipe. We will talk about Design Strategies, and about our system for testing, including the idea of debugging through testing. Last, we will give you a recipe for reviewing and editing your program before you turn it in.
