AWS Step Functions enhances the TestState API to support local unit testing of workflows, allowing you to validate your workflow logic, including advanced patterns like Map and Parallel states, without deploying state machines to your AWS account. AWS Step Functions is a visual workflow service capable of orchestrating over 14,000+ API actions from over 220 AWS services to build distributed applications and data processing workloads. The TestState API now supports testing of complete workflows including error handling patterns in your local development environment. You can now mock AWS service integrations, with optional API contract validation that verifies your mocked responses match the expected responses from actual AWS services, helping ensure your workflows work correctly in production. You can integrate TestState API calls into your preferred testing frameworks such as Jest and pytest and CI/CD pipelines, enabling automated workflow testing as part of your development process. These capabilities help accelerate development by providing instant feedback on workflow definitions, enabling validation of workflow behavior in your local environment, and catching potential issues earlier in the development cycle. The enhanced TestState API is available through the AWS SDK in all AWS Regions where Step Functions is available. For a complete list of regions and service offerings, see AWS Regions. To get started, you can access the TestState API through the AWS SDK, AWS CLI, or check out the AWS Step Functions Developer Guide.

AWS Step Functions now offers TestState in the AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions. This expansion allows customers operating in these regions to test individual states of their workflows without creating or updating existing state machines, helping to enhance the development and troubleshooting process for their applications. AWS Step Functions is a visual workflow service that enables customers to build distributed applications, automate IT and business processes, and build data and machine learning pipelines using AWS services. TestState allows developers to validate a state's input and output processing, test AWS service integrations, and verify HTTP task requests and responses. With TestState now available in the AWS GovCloud (US) Regions, customers can test and validate individual workflow steps. TestState supports various state types including Task, Pass, Wait, Choice, Succeed, and Fail, with tests running for up to five minutes. This feature is now generally available in the AWS GovCloud (US-East) and AWS GovCloud (US-West) Regions, in addition to all commercial regions where AWS Step Functions is available. To learn more about TestState and how to incorporate it into your workflow development process, visit the AWS Step Functions documentation. You can start testing your workflow states using the Step Functions console, AWS Command Line Interface (CLI), or AWS SDKs.
