SpringBoot provides excellent support for integration testing using @SpringBootTest annotation.

Testcontainers is a Java library that supports JUnit tests, providing lightweight, throwaway instances of common databases, Selenium web browsers, or anything else that can run in a Docker container.

Testcontainer allows us to use Docker containers within our tests. As a result, we can write self-contained integration tests that depend on external resources.
