Before Docker, configuring the environment for integration testing was painful - people were using fake database implementations, mocking servers, usually it was not cross-platform as well. However, than to Docker, now we can quickly prepare the environment for our tests. In this workshop, I would like to show how you can use Testcontainers - a popular testing library that harnesses Docker to easily, reliably, spin up test dependencies. You’ll go through the process adding powerful integration tests to your codebase (we’ll use a Spring Boot app) without the headache of managing external service dependencies manually. And get acquainted with all necessary Testcontainers concepts to write elegant, efficient, and reliable integration tests.
