Testing state machines locally in Step Functions
AWS Step Functions Local is a downloadable version of Step Functions that lets you develop and test applications using a version of Step Functions running in your own development environment. The local version of Step Functions can invoke AWS Lambda functions, both in AWS and while running locally. You can also coordinate other supported AWS services.
Note
Step Functions Local uses fake accounts that only work locally.
While running Step Functions Local, you can use one of the following ways to invoke service integrations:
-
Configuring local endpoints for AWS Lambda and other services. For information about the supported endpoints, see Setting Configuration Options for Step Functions Local.
-
Making calls directly to an AWS service from Step Functions Local.
-
Mocking the response from service integrations. For information about using mocked service integrations, see Using mocked service integrations for testing in Step Functions Local.
AWS Step Functions Local is available as a JAR package or a self-contained Docker image that runs on Microsoft Windows, Linux, macOS, and other platforms that support Java or Docker.
Warning
The downloadable version of AWS Step Functions is intended to be used only for testing and should never be used to process sensitive information.
Tip
Make sure you're using Step Functions Local version 1.12.0
The following topics describe how you can set up Step Functions Local using Docker and JAR file, and run Step Functions Local to work with AWS Lambda, AWS Serverless Application Model(AWS SAM) CLI Local, or other supported services.
