Spotify adopted container technology early on and built its own OSS framework for container orchestration called Helios. Not only do containers run many critical systems at Spotify, they also improve and accelerate development. We run containerized integration tests close to 400 times a day.

This talk covers how our Helios testing framework drives integration tests and spins up entirely self-contained environments during test runs. Developers can test services locally in an environment closely resembling the production stack; spin up dependent services like Cassandra, memcached, or even other containerized Spotify services; and even test their deployment and service discovery configurations.

Learn how this style of integration testing has increased our code quality and successful deployments.
