Hi Guys,

I am using Gatling 3.0.1 version on JDK 11 on windows machine.

I am currently testng GraphQl Subscription server with websocket connection, so as per journey, I do following steps in the script,

  1. Connect to Websocket
  2. Sendtext to websocket and this will give the response ““type”:“connection_ack”” and I did try a check function as
ws.checkTextMessage("ConnectionSuccessful").check(jsonPath("$.type").is("connection_ack"))

Many thanks Stephane, that’s working now if I give backslash in front of { as “\{” and “\}”.
