How to run your first API contract test in five minutes | SmartBear Swagger Contract Testing drift

Jul 30, 2026

Learn how to create, configure, and verify your first API contract test with SmartBear Swagger Contract Testing drift. Teams know contract testing prevents breaking API changes, but most stall out before they start – citing “we don't have time, we don't have the right skills, or we don't have the resources.” SmartBear Swagger Contract Testing removes that onboarding friction with drift, a capability that automates schema validation so you can adopt Interface-Driven Development (IDD), making your API specification the primary artifact of your build process in minutes.

This tutorial video series shows you the path to get started:

  • Installing drift via npx, a global npm install, or the Pact CLI extension
  • Authenticating to your Swagger Contract Testing (PactFlow) instance
  • Creating a drift.yaml file that points at an OpenAPI definition
  • Running drift verify against a live server.

By the end, you'll have a working drift test suite and know where to find the Pactflow, drift, and OpenAPI Parser AI skills to bring contract testing into your own agent workflows.
