This talk will examine TestContainers — a library that lets you run Docker containters from your JUnit (and not only JUnit) tests, providing instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

Apache, Spring, ZeroTurnaround, Zipkin, Zalando, Alfa Lab — only some of the companies that chose TestContainers. Come to the talk to figure out why!
