In this chapter, we’ll demonstrate how to implement a Stack using Test-Driven Development (TDD). We have found that the best way to understand TDD is to see it practiced and follow along step by step. The following are the steps we used to build a Stack using this method.
The Task

The operations include Push, Pop, Top, and IsEmpty. The Push function inserts an element onto the top of the Stack. The Pop function removes the topmost element and returns ...
