In this chapter you’ve learned a lot of different new things:
You’ve learned to play doctor and give your Ionic environment a health check.
You’ve learned a bit about strict typing and how helpful that can be, not only to support a very convenient code completion.
When debugging your app, you now know how to use Chrome and its DevTools.
You can watch your app in the Android Emulator and/or iOS Simulator and test native features in it.
You can test your app on a mobile device and in Ionic DevApp now.
Finally, you got into unit testing with Jasmine, TestBed and Karma and understand why tests can be the way to improve software quality and prevent software defects.

Any remarks or questions?
