Rails4アプリをGatlingで負荷テストする

前提

• Yosemite
• Rails 4.1.4
• Railsのログイン認証はDevise
• Gatling 2.0.0

準備

GatlingのサイトからLatest releaseのGatling bundleをダウンロード

テスト用のコード作成し、user-files以下に配置

import scala.concurrent.duration._

import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._

class Test1 extends Simulation {

  val basicAuthUser = "basic認証のユーザ"
  val basicAuthPassword = "basic認証のパスワード"
  val authUser = "ログインメールアドレス"
  val authPassword = "password0001"
  val baseUrl = "https://example.com/"
  val paramNameLogin = "user[email]"
  val paramNamePassword = "user[password]"

  object Login {

    val login = exec(http("request_0")
       .get("""/admin/login""")
       .basicAuth(basicAuthUser, basicAuthPassword)
       .check(regex("""<meta content="(.*?)" name="csrf-token" />""")
       .saveAs("auth_token")))
       .exec(http("request_1")
       .post("""/admin/login""")
       .header("X-CSRF-Token", "${auth_token}")
       .formParam(paramNameLogin, authUser)
       .formParam(paramNamePassword, authPassword)
       .basicAuth(basicAuthUser, basicAuthPassword)
       .check(status.is(200)))

  }

  object Shop {

    val headers_0 = Map(
      """Accept""" -> """text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8""",
      """Cache-Control""" -> """max-age=0""")

    val headers_1 = Map("""Cache-Control""" -> """max-age=0""")

    val shops = exec(http("request_2")
       .get("""/admin/shops""")
       .basicAuth(basicAuthUser, basicAuthPassword)
       .check(status.is(200)))
  }

  val httpProtocol = http
    .baseURL(baseUrl)
    .inferHtmlResources()
    .acceptHeader("""image/webp,*/*;q=0.8""")
    .acceptEncodingHeader("""gzip, deflate, sdch""")
    .acceptLanguageHeader("""en-US,en;q=0.8,ja;q=0.6""")
    .userAgentHeader("""Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36""")

  val scn = scenario("Login").exec(Login.login)
  val scn2 = scenario("Shop").exec(Shop.shops)

  setUp(
    scn.inject(atOnceUsers(1)),
    scn2.inject(atOnceUsers(5))
  ).protocols(httpProtocol)

}

実行
