In this chapter, we begin with various models of the software development life cycle in terms of the implications these life cycles have for testing. We took a general view in Chapter 1, where we identified three levels (unit, integration, and system) in terms of symmetries in the waterfall model of software development. This view has been relatively successful for decades, and these levels persist; however, the advent of alternative life cycle models mandates a deeper look at these views of testing.
