It demonstrates how to run Behavior-Driven tests against a REST API using Cucumber.
The goal is to develop a Web service that exposes resources to manage a baking account. We should be able to create an account, deposit money and transfer money to another account. The account must have a name and every input from clients should be validated. These requirements should be specified using Gherkin syntax and executed by Cucumber and JUnit with code coverage collected by JaCoCo.
The application is based on Spring Boot (MVC, JPA, Jakarta Validation), persists data in a Postgres database with migrations managed by Flyway. Edge cases are testing using JUnit and TestContainers and no manual configuration is required to run them.
