In this chapter, we learned how to activate code coverage. We used the data from a measurement to improve our code. By activating the presentation of the coverage data in the editor, we figured out which lines aren't tested by the test suite.
Next, we set up Xcode Server and added a bot to get the advantage of a continuous integration server. We took a look at how we can use Xcode Server to host our repository.
Finally, we used fastlane to automatically create and load provisioning profiles and build and submit our app for the TestFlight review.
In the next and final chapter, we will discuss what we can do to learn more about testing and the other approaches that are included in writing tests.
