Testcontainers

Testcontainers is a Java library that allows developers to easily create and manage temporary instances of common software components, like databases or message queues, within virtualized environments called containers. By using Testcontainers, developers can run tests that closely mimic how their applications will behave in a real environment, ensuring more reliable and accurate results. It simplifies the testing process by automatically setting up and tearing down these components, which helps to avoid conflicts and makes it easier to run tests in isolation without affecting other parts of the system.
