No Websocket response is obtained in JMeter

Question

1. If a WebSocket request-response Sampler is used, the next sampler fails.
2. The same requests pass on using WebSocket Single Write Sampler instead of WebSocket request-response Sampler.
3. Even when the WebSocket Single Write/Read Sampler passes, there is no response obtained for any of the samplers.

Please advice on what can be done. I am referring to the document -

Answer 1

If you're referring the article and hitting the echo.websocket.org I believe now you need to use wss protocol

If you're testing your own server unfortunately we are not able to help unless we see the

• full test plan

• JMeter log file (better with debug logging for websocket plugin enabled, it can be done by adding the next line to log4j2.xml file in bin folder of your JMeter installation)

   <Logger name="eu.luminis" level="debug" />
  

• network dump from browser developer tools or external sniffer tool like Wireshark or Fiddler for both browser/application and JMeter
