Database Integration Test with DBRider

In this lesson, we’ll create the skeleton of a database integration test using a test framework called DBRider. We’ll use this test to drive out the creation of a database table and database user. We’ll be working towards implementing the WordRepository interface, which will access words stored in a Postgres database.

Skeleton of a database integration test

Previously, we created a domain model for our Wordz application, using hexagonal architecture to guide us. Instead of accessing a database directly, our domain model uses an abstraction, known as a port in hexagonal terminology. One such port is the WordRepository interface, which represents stored words for guessing.
