FAQPage Schema
How do I validate an OpenAPI schema for AWS API Gateway without deploying?▼

You can validate OpenAPI schemas offline by generating contract tests that check request and response shapes, required fields, and security definitions against your specification without requiring live AWS deployments.

What is contract testing for AWS Step Functions and how does it work?▼

Step Function contract testing validates input and output contracts using jsonschema and pydantic, ensuring your state machine data adheres to defined schemas and required field constraints before deployment.

Can I test SAM and CloudFormation definitions for schema mismatches offline?▼

Yes, you can analyze SAM and CloudFormation definitions to verify request and response shapes, enforce enum constraints, and validate security definitions entirely offline.

Do I need a live AWS environment to run API contract tests?▼

No, you do not need a live AWS environment because this offline validation approach analyzes API specifications directly to catch schema mismatches and ensure required fields are present.

How do I generate contract tests for my swagger.yml file?▼

You generate contract tests for swagger.yml by analyzing the OpenAPI specification to validate schemas, request and response shapes, required fields, and security definitions using jsonschema and pydantic.
