OpenAPI is more than just a documentation tool - even though it's great for that! As the tooling for OpenAPI version 3 has matured, there are now more opportunities to use OpenAPI to make your API development faster, easier, and more resilient. In this talk you'll learn how to use the OpenAPI spec and tools in the Open API ecosystem to power: - Mock servers to test your API before it exists - Integration tests to ensure that your API responses meet your specification - Validation logic - Documentation

Great talk about how to write or generate and use Open API specs for various purposes.

It may be worth going into a bit more detail about JSON Schema, the iterative progression of Open API v3 toward conformance with JSON Schema, and what the potential implications of that may be, especially with respect to tooling.
