Tavern

Automated API testing in concise YAML files

About Tavern

A command-line tool and Python library for automated testing of APIs, using concise YAML test files to describe requests, validations and stages for RESTful services and integrations. Because the code is openly available, it can be audited, extended and run on private infrastructure, which makes it attractive to teams with privacy or compliance needs. It is commonly adopted through containers or packages, evaluated against commercial alternatives and kept because it solves a focused problem reliably at scale.
