Comprehensive testing strategies for AWS Lambda durable functions using local and cloud test runners with TypeScript
This pattern demonstrates comprehensive testing strategies for AWS Lambda durable functions using the Durable Execution SDK testing library.
It includes five key testing scenarios: basic workflows with wait operations, retry logic validation, callback testing for external events, parallel operations testing, and nested function composition.
The pattern uses LocalDurableTestRunner for fast local testing with time-skipping and CloudDurableTestRunner for integration testing against deployed functions.
All tests demonstrate best practices including operation inspection, mock external dependencies, callback simulation, and function registration for nested workflows.
