Integration Tests with Docker Testcontainers
About the presentation
Unit testing is fine, but without proper integration testing, especially if you work with external resources like databases and other services, you might not know how your application will actually behave once it has been deployed to the real production environment.
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, thanks to Docker, now we can quickly prepare the environment for our tests.
In this talk I would like to show how you can use Testcontainers – a popular Java testing library that harnesses Docker to easily, reliably, spin up test dependencies.
- How you can use Testcontainers
- How to setup a development and testing environment without the need to install external applications
- That nowadays using real software for integration tests might sometimes be preferable over mocking out external dependencies
