+Testing is divided into the following categories.
+|Test case|Description|
+|-----|----------|
+|Core interface test|Mainly including the addition, deletion, modification, query, subscription, and other operations of the HTTP API interface for core data(PLUGIN, NODE, GROUP, TAG)|
+|Southbound DRIVER test||
+|Northbound APP test||
+|Plugin specific test case|Such as OPC UA specific device discovery, can different devices be connected normally|
+

+Enter the neuron/build directory.
+Install Mosquito software.
+```shell
+$ sudo apt-get install -y mosquitto
