Summary
In this chapter, we spent our efforts extending the BookSwap application. We began by discussing what a typical user journey for a user will be, added a PostgreSQL database to it, and configured it to run with Docker. Then, we explored the Godog testing library, which makes it easy to write BDD-style tests, as well as E2E tests. We made use of Godog to verify that users are able to sign up on the BookSwap application, making use of the code generation abilities of Godog. Finally, we briefly discussed the challenges of creating database start positions and assertions directly at the database level.
In Chapter 7, Refactoring in Go, we will discuss tools and techniques for code refactoring and how to break up monoliths into multiple services. This will give us a realistic understanding of how to rely on our tests to verify that refactoring does not cause errors or break existing functionality.
