In this chapter, we covered the process of getting your application deployed and tested. When we first started building our product, we designed a flowchart that showed all of the flows and processes going on. We can then use this to ensure that we test every path through our application before deploying. Ideally, we'd do this using automated testing.

We also learned how to use Twilio's App Monitor and Triggers once our application is live to track errors, plus how to use the Request Inspector to dive deep into these errors and work out how to fix them, along with included tips on some of the most common errors.

In the next chapter, you'll find some helpful online resources that will help you get the most of this book and continue to improve your Twilio projects.
