Before we start

Difficulty: Beginner | Easy | Normal | Challenging

Keywords and Terminology:

Mocking: A fake response to the method call for of an object, allowing the checking of a particular method call or property

Prerequisites:

• None, although knowing something about Mocking would be useful, and if you are interested I’ve mocked using this set of techniques
