Unit testing is fine, but without proper integration testing, especially if you work with external resources like databases and other services, you might not know how your application will actually behave once it has been deployed to the real production environment.

Testcontainers is a popular multi-language (JVM, Go, .NET, NodeJS, and more!) testing library that provides lightweight, throwaway instances of databases, message brokers, Selenium web browsers, or anything else that can run in a Docker container, effectively replacing mocks with real technologies. In this talk we will explore how Testcontainers helps developers gain more confidence during the development, compare it to ephemeral environments, and all of that without writing a single line of YAML!
