The goal of the validation project is to create an environment which can be used to answer the question, "how do you know that your model works"? For example, say you have created a CSMA net device. How do you know that your net device is behaving according to your design without having to generate huge volumes of trace files. How do you determine that your model is handling all of the exceptions that you intend it to?
Testing in ns-3 will provide you with tools to make these determinations.
