I am using Jmeter for the load testing of an application which includes web socket connection.

When trying to read the data in a frame using Single Read Sampler,got an error Response code: No response Response message: Read timeout, no response received.

Can anybody help me in solving this issue?

As per JMeter WebSocket Samplers - A Practical Guide

WebSocket Single Read Sampler - Receives text or binary WebSocket frames

So I can think of 2 reasons:

  1. Your Single Read Sampler configuration is not correct, i.e. wrong protocol/host/port/path/etc. Cross check the settings with i.e. browser developer tools. For example you're using wss protocol with port 80 however the port should be 443 or something like that
  2. Your application doesn't automatically send frames over the established connection, to wit it requires some input from your side. If this is the case make sure to send something to the endpoint using i.e. WebSocket Single Write Sampler

You might find Single read sample.jmx example test plan useful.

If you will be experiencing problems consider adding the following lines to log4j2.xml file (lives in "bin" folder of your JMeter installation)

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

then restart JMeter and re-run your test and look into jmeter.log file - it should contain verbose debugging information on what's going on under the hood, most probably you will be able to figure out the cause of the problem from there.
