In this chapter we have explored the role of testing within the software development life cycle. We have looked at the basic steps in any development model, from understanding customer needs to delivery of the final product. These were built up into formally recognisable models, using distinct approaches to software development.
The V-model, as we have seen, is a stepwise approach to software development, meaning that each stage in the model must be completed before the next stage can be started, if a strict implementation of the model is required. This is often the case in safety-critical developments. The V-model typically has the following work-products and activities:
