AWS SAM LOCAL DYNAMODB TESTING FULL

The identity and address are successfully validated using a Lambda function.

In this example, you test a scenario in which: Note the workflow task names in the diagram, such as DetectSentiment, which are important when defining the mocked responses.

The full workflow definition is available in the code repository. The following Step Functions Workflow Studio diagram shows the control logic: No record is added to the Amazon DynamoDB table. If the sales lead data is invalid or a negative sentiment is detected, it publishes events to EventBridge for notification. The event is published to Amazon EventBridge to notify subscribers. If the comments have a positive sentiment, it adds the sales leads information to a DynamoDB table for follow-up. It uses the sales lead’s comments as input for sentiment analysis. If valid, it uses Step Functions’ AWS SDK integration for Amazon Comprehend to call the DetectSentiment API. Using the sales lead data, the workflow first validates the contact’s identity and address. This triggers the sample workflow execution using input data, which provides information about the contact. In this example, new sales leads are created in a customer relationship management system. You can find the code used in this post in the Step Functions examples GitHub repository. You can combine them into test case scenarios to validate workflow control and data flow definitions. This allows developers to define sample outputs from AWS service integrations. Today, AWS is releasing Mocked Service Integrations for Step Functions Local. Often, developers want to test the control and data flows of their state machine executions in isolation, without any dependency on service integration availability. However state machines that use service integrations like AWS Lambda, Amazon SQS, or Amazon SNS require Step Functions Local to perform calls to AWS service endpoints. Additionally, developers use Step Functions’ input and output processing features to transform data as it enters and exits tasks.ĭevelopers can test their state machines locally using Step Functions Local before deploying them to an AWS account. This allows for precise workflow execution with deterministic results. Developers want to build and test control flow logic for workflows using branching logic, error handling, and retries.
