I have a back end application (only back end) which sends data to customers by WebSocket.
I testing this application using JMeter. In Jmeter I added plugin WebSocket Sampler by Peter..
Previously I am sending this data to customers by Postman.
In my Json file incluge data about event, in which customers can subscribe. I have one question: How can I do it, that data, which is send in postman (in json file) will be send in JMeter?



Is it correctly way to read my json file in Jmeter?
If not: Why not and how I can improve this?




  1. How I can the best to process data - to variable from my json file?

There is __FileToString() function, you can kill two birds with one with it, to wit:




  1. Read a file from the file system

  2. Store file contents into a JMeter Variable


For example the following expression:



${__FileToString(file.json,,myVar)}


will read file.json from JMeter's "bin" folder and store its contents into ${myVar} JMeter Variable:



enter image description here





If you have multiple JSON files and want multiple JMeter threads to send different files - the easiest way is going for Directory Listing Config plugin (can be installed using JMeter Plugins Manager)
