TestContainers – integration testing without the hassle
|Cloud, Containers & Infrastructure|
|Thursday from 18:50 til 19:20|
Unit testing is nice, but without a proper integration testing, especially if you work with external resources like databases and other services, you might not know how your application will behave once it's deployed to the real environment.
Before the Docker, configuring the environment for integration testing was painful – people were using fake database implementations, mocking servers, usually it wasn't cross-platform as well. But now, we can easily prepare the environment with Docker for our tests.
In this talk I would like to spread the word about TestContainers ( https://github.com/testcontainers/testcontainers-java ) – 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.
A year ago we (ZeroTurnaround) decided to join our Docker-based test engine and TestContainers, and now it's open-sourced, available to everyone, so you can test your apps like we do :)
