Communication Test Tools

Introduce

Communication testing tools, support server and client mode for a variety of communications, includ TCP, UDP, MQTT, Websocket, SignalR, ZeroMq, and support mock Http response, which can be used to test http requests or test WebApi.

The communication interface in the application is divided into two parts, the left side is the server area and the right side is the client area.

How to use
