Summary
In this chapter, we described the techniques to help test your D3 code base and to keep it healthy over the lifespan of your project. We also went step-by-step through a bootstrap project to help you get started with these examples, and we took a look at a methodology for structuring your work.
Our recommendations are based on many years of experience and many projects delivered using D3. We strongly recommend that you follow good software patterns and focus on tests; this will allow you to perfect your craft. Quality is in your hands now. With this, we say goodbye, and thank you for reading!
