Testcontainers

What is Testcontainers?

Testcontainers is a set of open source libraries that provides easy and lightweight APIs for bootstrapping local development and test dependencies with real services wrapped in Docker containers. Using Testcontainers, you can write tests that depend on the same services you use in production without mocks or in-memory services.
