Testcontainers: The Best Way to do Integration Testing
Testcontainers is a Java library that supports JUnit tests by providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container. They help with integration tests by making it easy to download and set up database containers, containerized web browsers, and more.
The best part about the Testcontainers project is that the code is (mostly) simple to write and then just works. You add the proper dependency, instantiate the desired container as part of your tests, and run as usual. Demos will include Spring Boot projects with different databases and more.
