Crossplane has become the foundation of many Internal Developer Platforms (IDPs). A requirement for any IDP in production is the ability to make changes and upgrades to the platform with confidence.

This talk will cover testing and release patterns based on our experience building production-ready environments across a range of Crossplane users.

We’ll cover the lifecycle of a Crossplane Composition upgrade, from local commit to pull request to target customer environment, end-to-end testing tools, handling API changes, and how to control updates to customer environments.

For quite a while, testing Crossplane Compositions meant relying exclusively on costly end-to-end layers. In this talk, we're unveiling new unit testing capabilities that allow you to evaluate and test your Composition code in complete isolation.
