Part One

Setting the Context

• Chapter 1 Principles of Testing
• Chapter 2 Software Development Life Cycle Models

This part of the book sets the context for the entire book. We start Chapter 1, Principles of Testing, by discussing the changes in the software scenario over the last few years and the demands that these changes make on software quality. We translate these demands into eleven basic principles which provide anchors to rest of the chapters. In Chapter 2, Software Development Life Cycles, we define key terms like verification, validation, quality assurance, and quality control, go into the details of the various life cycle models and the implication of these models on verification and validation activities. We also introduce the concepts of entry and exit criteria that will be necessary to understand the different phases of testing later in the book.
