Steps:
1) Stick the response in a file and put it in request-bodies or bodies (depending on your gatling version)
2) Include the following header in httpProtocol
3) use the following syntax in your scenario
val scn = scenario("Test-WS")
.exec(http("Test-WS")
.post("/")
.body(ELFileBody("demo-WS/soap.xml"))
.check(xpath("//totalResults/text()").find.not("0")))
setUp(scn.inject(atOnceUsers(1))).protocols(httpProtocol)Also, you can parametrize the response (objects in file) with string interpolation (eg: "${myVar}") and use feeder for different variables.
Hope that helps
