[Gatling] Customize your scripts based on scenario
Sometimes record function may not fulfill your requirement, in this case you need write scala script yourself according to gatling document.
Below is a simple sample to test two APIs: employee & health check
package me.hongmeng.stress.test import io.gatling.core.Predef._ import io.gatling.http.Predef._ class SimpleSimulation extends Simulation { val hostname = "http://localhost:8080" val httpProtocol = http .baseURL(hostname) .inferHtmlResources() .acceptHeader("*/*") .contentTypeHeader("application/json") .userAgentHeader("Gatling/2.3.1") val headers = Map("accept-encoding" -> "gzip, deflate", "cache-control" -> "no-cache") val employeeScenario = scenario("create_experiment_simulation") .exec( http("employee") .post("/v1/employees") .headers(headers) .body( StringBody("{"name": "xiaowang","major": "software"}") ) ) val healthScenario = scenario("health_simulation") .exec( http("health_check") .get("/actuator/health") .headers(headers) ) setUp( employeeScenario.inject(atOnceUsers(10)), healthScenario.inject(atOnceUsers(10)) ).protocols(httpProtocol) } -
