SchemathesisFiscal Host: Open Source Collective 501(c)(6)
Schemathesis is a modern API testing tool for web applications built with Open API and GraphQL specifications.
It reads the application schema and generates test cases, which will ensure that your application is compliant with its schema.
The application under test could be written in any language; the only thing you need is a valid API schema in a supported format.
Simple to use and yet powerful to uncover hard-to-find errors thanks to the property-based testing approach backed by a state-of-the-art Hypothesis library.
