Testing AWS AppSync GraphQL APIs with AWS Amplify

Building scalable applications requires robust, reliable APIs that perform predictably under any conditions. Integrating AWS AppSync with AWS Amplify simplifies your backend development, but ensuring your GraphQL schemas, resolvers, and queries work flawlessly requires a structured approach to testing. This course guides you through the essential concepts and practical workflows needed to validate your cloud APIs with confidence. You will transition from manually testing API endpoints to implementing structured testing strategies that catch bugs early in the development lifecycle. This includes setting up local mocking environments so you can test your schema changes without deploying to the cloud every time. What you'll learn: - Understand the core architecture of AWS AppSync, GraphQL schemas, and AWS Amplify integration - Configure local mocking environments using the Amplify CLI to test queries and mutations locally - Write automated unit and integration tests for GraphQL resolvers and data sources - Apply modern testing patterns to validate API authentication, authorization rules, and user permissions - Debug common schema mismatches and resolver errors before deploying to production environments The course begins with foundational concepts, introducing GraphQL terminology and AWS AppSync architecture, before progressing to hands-on testing workflows, resolver validation, and automated test suites. This course is designed for beginner to intermediate developers who want to learn how to test AWS-backed GraphQL APIs. No prior cloud testing experience is required, though a basic familiarity with JavaScript and APIs will help you get the most out of the material.
