Live data local testing is now available for public preview in Azure Stream Analytics Visual Studio tools, which enables you to test jobs locally from the IDE using live event streams from Azure Event Hub, IoT Hub, and Blob Storage. The new local testing runtime can read live streaming data from the cloud or from a local static file. It works the same as the cloud runtime Azure Stream Analytics and therefore supports the same time policies needed for many testing scenarios. The query runs in a simulated environment suitable for a single server development environment and should only be used for query logic testing purposes. It is not suitable for performance/scalability and availability testing.
