• Mocking of AWS service integrations with optional API contract validation.
• Integration with popular testing frameworks such as Jest and pytest, and CI/CD pipelines.

What to do

• Integrate TestState API calls into your testing frameworks and CI/CD pipelines.
• Use the TestState API to mock AWS service integrations and validate responses.
• Access the TestState API through the AWS SDK, AWS CLI, or the AWS Step Functions Developer Guide.
