 # Test live data locally using Azure Stream Analytics tools for Visual Studio (Preview)
 
-Azure Stream Analytics tools for Visual Studio allows you to test jobs locally from the IDE using live event streams from Azure Event Hub, IoT Hub, and Blob Storage. Live data local testing can't replace the [performance and scalability testing](stream-analytics-streaming-unit-consumption.md) you can do in Azure portal, but you can save time during functional testing by not having to return to the Azure portal each time you want to test your Stream Analytics job. This feature is in preview and shouldn't be used for production workloads.
