How to automate API regression tests without code | SmartBear Swagger Functional Testing

Learn how to automate API regression tests without writing code. In this tutorial, you'll use an OpenAPI specification to build automated API tests with SmartBear Swagger Functional Testing using a visual, low-code workflow.

What this solves:

• No automation skills needed – Build real tests with a visual, low-code workflow instead of scripts.
• Less manual setup – Import endpoints directly from your Swagger or OpenAPI spec.
• Fewer brittle tests – Capture dynamic values, like a customer ID, and reuse them automatically in later steps.
• Stronger data integrity checks – Built-in assertions confirm data created in one call can be retrieved in another.
• Design and testing alignment – Tests build straight from the API definition as it evolves.
• Faster regression cycles – Grouped test suites run automatically in CI/CD on every API change.
