Fixture Factories for Faster End-to-End Tests

Explore fixture factories for faster end-to-end testing in service-oriented architectures in this EuroPython 2017 conference talk. Dive into the challenges of maintaining test fixture data across multiple services and discover developer-friendly approaches to generate more efficient and accurate test data. Learn how to implement fixture factories, integrate them with pytest, and leverage parallel test execution to significantly reduce runtime. Gain insights into improving test maintainability, adaptability, and overall code quality while addressing common pitfalls in end-to-end testing for distributed systems.
