In this chapter, we explored the benefits that good testing brings to our company, team, products, and users. Good testing will always make our products better and our users happy.

We learned how to apply TDD to our software development process and the importance and impact it has on the quality of our apps. You should always remember that TDD is composed of three colored phases: the red phase, which makes your test fail; the blue phase, which makes your test pass; and lastly, the green phase, which refactors and cleans your code.

We also learned about the testing technologies that Aurelia uses for development and learned how to use them independently. Jasmine is the testing framework and Karma is used as the test runner.

We practiced with a real testing example of an Aurelia component and we explored some debugging options.

Now that we are in good shape and know how to style and test Aurelia applications, it's time to become real experts in creating Aurelia components. So, keep reading!
