Summary

In this chapter, we briefly talked about software design and a few basic design principles. We implemented a fully-functional version of the board game Connect4 using two approaches: traditional and test-driven development.

We analyzed both solutions in terms of pros and cons, and used a Hamcrest framework to empower our tests.

Finally, we concluded that good design and good practices can be performed by both approaches, but TDD leads developers to the better way.
