API-Schema-Based Testing with Schemathesis

Explore property-based testing for APIs using schemas in this 28-minute EuroPython 2020 conference talk. Learn how to automatically generate test scenarios from API schemas, enabling faster and more powerful testing. Discover the schemathesis library, which leverages hypothesis and hypothesis-JSONSchema extension strategies, and compare it with other tools like swagger-conformance. Gain insights into the future of GraphQL support and understand how formal API schemas provide value beyond documentation. Follow along with a demonstration of the CLI interface, pytest examples, and stateful testing techniques to enhance your API testing practices.
