AWS IoT Core Device Advisor now supports the capability to run multiple test suites at the same time. Device Developers can use this capability to complete testing faster by testing multiple devices simultaneously. Developers can also test their devices more comprehensively by using new MQTT test cases such as a test to validate the device behavior when the device is disconnected from the server side. Device Advisor console also provides a new and simpler way for developers to quickly review and create an IAM role in few clicks, enabling developers to grant permissions to Device Advisor for connecting with AWS IoT Core on behalf of their test devices.
