The Swagger Revolution: How API Specs Became a Testing Superpower with Tony Tam


Listen Later

In this episode of the Cloud Native Testing Podcast, Ole Lensmar sits down with Tony Tam, creator of Swagger API (now known as the OpenAPI specification) and a pioneer in API specification standards, to explore the unexpected ways Swagger transformed software testing.

Tony shares the origin story of Swagger: from its roots in solving REST client generation to how it became a foundational tool for testing, documentation, and collaboration across teams. He explains how OpenAPI specs gave rise to a new generation of spec-driven testing, enabling everything from automated validation to smarter negative test cases.

Whether you're maintaining legacy services, scaling microservices, or figuring out how to test AI-powered workloads in distributed environments, Tony’s insights into API resilience, tooling, and testing culture are not to be missed.
