JMeter pressure test based on WebSocket protocol

WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex). Browsers and servers only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two. In this WebSocket agreement, there are two major benefits to our Instant service: 1. Headers that communicate with each other are very small-about 2 Bytes2. Server Push Browser Request

JMeter Test Webocket Protocol

The jmeter itself does not support the WebSocket protocol, so you need to install a third-party plugin with 6 dependent packages. : https://jmeter-plugins.org/

After the download is complete, drop it directly into the JMeter \lib\ext\ directory. This plugin is available for restart JMeter.

Start JMeter, right-click Test Plan, add->threads (users), thread group->sampler->websocket Sampler

WebSocket Sampler Page

Main Options Description:

1, WebServer
(1) address or name of the destination server sent by server name or Ip:websocket
(2) port number the Port Number:websocker server listens on. (typically an HTTP 80 port, which can be obtained via Wireshark packets)


2. Timeout:
(1) connection– The maximum time, in milliseconds, that JMeter waits for a connection to complete after sending a connection request.
(2) Response-The maximum wait time for the response message.


3. WebSocket Request
(1) implementation– only supports RFC6455 (V13), the latest version of the WebSocket protocol standard.
(2) protocol– has WS and WSS, the WS prefix is the distinguished identity of the WebSocket connection, and the WSS prefix is the distinguished identity of the WebSocket secure connection. Fill in according to your actual situation
(3) Streaming connection– Select this TCP session to maintain, if the hook on the identity of the connection will always exist, if not checked, then the first response after the link will be closed.
(4) Request data: Fill in the requests to be sent, to communicate with the development of good, this is what format message.


4.WebSocket Response
(1) Response pattern– Sampler will wait for the message containing the identity and continue to communicate (or until timeout, the connection is closed)
(2) Close Connection pattern– If the message returned by the server contains such a character, it ends the session.
(3) Message backlog– defines the maximum length that the server returns message retention.

After adding WebSocket sampler, add a View results tree and run to see the results.
