DB Integration Tests with Spring Boot and Testcontainers

Date: 2021-11-08

This tutorial demonstrates using Testcontainers with Spring Boot to perform integration tests on JPA repositories. It uses a PostgreSQL container managed by Testcontainers, eliminating the need for a pre-existing database. The example involves a simple REST API application persisting data to a database. The setup includes configuring dependencies in pom.xml, database properties in application.properties, and creating a Book model, repository, and test classes. The tutorial guides you through creating a base test class for container management and writing JUnit tests. Docker must be running. The complete application is available for download.
