Testing AWS AppSync GraphQL APIs with Amplify

Testing backend services is critical to building secure, scalable applications, yet testing cloud-native GraphQL APIs often feels complex. This text-only course simplifies the process, showing you how to systematically verify your AWS AppSync APIs using AWS Amplify. You will transition from manual API checks to confident, automated testing of queries, mutations, and access control policies. In this course, you will learn to test three essential patterns: standard queries, complex queries utilizing custom secondary indexes, and fine-grained, group-based authorization rules. We begin by establishing foundational cloud testing concepts, ensuring you understand the core architecture before writing test cases. What you'll learn: - Understand the core architecture of AWS AppSync and how it integrates with AWS Amplify - Test basic GraphQL queries and mutations to verify data flow - Query custom secondary indexes to retrieve specific data structures - Verify group-based authorization rules to ensure secure data access - Implement automated testing workflows to catch breaking API changes early This course guides you through structured readings, clear code examples, and step-by-step testing scenarios, taking you from initial API configuration to robust, secure test suites. It is designed for developers who are new to testing cloud APIs and want to build reliable, production-ready backends. No prior experience with AWS testing is required, though a basic understanding of GraphQL concepts will help you get the most out of this course.
