Testcontainers is a library that supports integrated tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container. We aim to make integrated testing less painful!

Testcontainers' main, and most mature, implementation is for Java, but we have a growing community of forks in other languages.

Many tens of thousands of builds per day run with Testcontainers, supporting countless companies and open source projects around the world.
