Join us as we dive into the new local unit testing capabilities for AWS Step Functions with Jas Narula, Product Manager from the Step Functions team. We explore how developers can now test their workflows locally using the enhanced Test State API, moving beyond the limitations of the discontinued Step Functions Local container. Jas walks us through the new mocking capabilities, support for advanced states like Map and Parallel, and how this API-based approach gives you the same production runtime for testing. We also discuss the partnership with LocalStack for offline testing, the developer experience with popular testing frameworks like PyTest and Jest, and why this new approach makes Step Functions development more like traditional test-driven development. Whether you're orchestrating Lambda functions, calling Bedrock APIs, or building complex business workflows, this episode shows you how to test with confidence before deploying to the cloud.
