Spring Boot 3.1.0 introduced support for Testcontainers to simplify local development and testing. Testcontainers helps in writing tests using real dependencies instead of mocks, but it may also increase the test execution time.

One of the many reasons for the huge popularity of Spring and SpringBoot is its great support for Testing. We can write unit tests using Mockito without requiring any Spring features. And, we can write Integration Tests using Spring testing support by creating Spring ApplicationContext.
