AWS has launched a Step Functions extension for VS Code, providing an enhanced local development experience for Step Functions.The extension allows developers to visualize workflows in VS Code, run Step Functions locally, and support live debugging.One of the notable features is state-by-state testing, which allows developers to validate the output of individual states, reducing development time.However, the extension is currently limited to VS Code, and there are calls for AWS to expand support to IntelliJ, Eclipse, and other popular IDEs.
