Module Overview

This week we will discuss interchangeable parts and testing. You will learn to distinguish between glass-box and black-box testing, which will help you to understand how interchangeability of parts depends upon abstraction barriers and information hiding. You will also learn benefits and limitations of execution-based testing.
