Thank you for your response.

But by POSTing parameters(JSON string and two other) like that,it is not sending any request to REST

i got 415 error…

so please tell me how to POST parameters using POST

my parameters are

param1=user1
param2=1
param3=5

param4=[{“level”:“levelname1”,“number”:“two”},{“level”:“levelname2”,“number”:“three”}]

note: param4 is JSON string

by sending those parameters in POST, i want to test my REST…

in my case response also as JSON only…

Given:

.body(StringBody(""" {“offerId”: “123”, “membershipId”: “123”, “osName”: “iOS”, “osVersion”: “8.02”} “”")).asJSON

can I parameterize membershipId like this:

.body(StringBody(""" {“offerId”: “123”, “membershipId”: “${memberID}”, “osName”: “iOS”, “osVersion”: “8.02”} “”")).asJSON

given a .csv file with contents:

memberID
123
123
123
123

and given

val scn = scenario(“Scenario”)

.feed(csv(“membershipId.csv”).random)

.
.
.

Again: yes, that’s exactly what StringBody is intended for…

You’d have to first store a “dateVar” attribute in the session, and then use the proper Gatling EL syntax in your template (${dateVar} instead of $dateVar).
Check the documentation.
