This project contains code samples for testing serverless applications using TypeScript.
| Project | Description |
|---|---|
| TypeScript Test Samples Starter Project | This project contains an introductory example of TypeScript tests written for AWS Lambda and Amazon API Gateway. This is the best place to start! |
| Calling Cloud Resources from Local Tests | This project demonstrates testing an AWS Lambda function handler locally which calls remote cloud services. The Lambda function handler makes a call to a DynamoDB table in the cloud in the integration test. |
| Testing Serverless architectures with Datadog Synthetic Testing and Monitoring | Creates Synthetic Tests and Monitors in Datadog to ensure Serverless services are functioning properly in a real, AWS environment. |
| AWS AppSync, Amazon Cognito, AWS Lambda | Examples of TypeScript tests written for AWS AppSync with authentication provided by Amazon Cognito. |
| Amazon Kinesis, AWS Lambda, Amazon DynamoDB | Testing a small data processing system that processes records from an Amazon Kinesis Data Stream and stores the processed records in an Amazon DynamoDB table. |
| Using LaunchDarkly for Testing with AWS Lambda | Use LaunchDarkly feature flags to test new code and features within a serverless application using AWS Lambda. |
| AWS Step Functions Local Testing using Jest | Shows how to run Step Functions local tests with mocks using Jest |
These projects have examples of unit and integration tests for API based applications.
| Project | Description |
|---|---|
| javascript-http-sam [External] | An implementation of the backend API using AWS API Gateway HTTP endpoint, Node.js and AWS SAM. |
| Testing Amazon Api Gateway, AWS Lambda, and Amazon DynamoDB | This project contains examples of TypeScript unit and integration tests written for AWS Lambda in the context of an Amazon API Gateway API and an Amazon DynamoDB table. |

In a synchronous system, a calling service makes a request to a receiving service and then blocks, waiting for the receiver to complete the operation and return a result. In contrast, in an asynchronous system, a caller makes a request to a receiving system, which typically returns an immediate acknowledgement but then performs the requested operation at a later time. Asynchronous systems are frequently designed using event-driven architectures. These types of systems have several advantages including increased reliability, greater control over load processing, and improved scalability. However, testing these systems can present unique challenges.

|---|---|
| Async Integration Test Sample | In this pattern, an AWS Lambda function is configured to be an event listener to receive the asynchronous System Under Test's output data. |
| Testing a Stream-based Architecture | This project contains an example of testing a data processing system that processes records from an Amazon Kinesis Data Stream and stores the processed records in an Amazon DynamoDB table. |
| Schema and Contract Testing | This project contains introductory examples of TypeScript unit tests demonstrating schema and contract testing. |
