xUnit Test Patterns: Refactoring Test Code

Footnotes

Preface

¹ The Pattern Languages of Programs conference.

² Technically, they are not truly patterns until they have been discovered by three independent project teams.

³ The testing function is sometimes referred to as "Quality Assurance." This usage is, strictly speaking, incorrect.

⁴ The Law of Raspberry Jam: "The wider you spread it, the thinner it gets."

Introduction

¹ A small percentage of the unit tests may correspond directly to the business logic described in the requirements and the customer tests, but a large majority tests the code that surrounds the business logic.

² A change in behavior could occur because the system is doing something different or because it is doing the same thing with different timing or sequencing.
