[英]Creating dynamic POST /users calls with Gatling in Scala
I am using Gatling to generate a large number of users to test performance issues on my product. 我正在使用加特林(Gatling)生成大量用户,以测试产品上的性能问题。 I need to be able to dynamically create users with unique fields (like 'email').
我需要能够动态创建具有唯一字段(例如“电子邮件”)的用户。 So, I'm generating a random number and using it, but it isn't being re-instantiated each time, so the email is only unique on the first pass.
因此,我正在生成一个随机数并使用它,但是不会每次都重新实例化它,因此该电子邮件仅在第一次通过时才是唯一的。
object Users {
def r = new scala.util.Random;
def randNumb() = r.nextInt(Integer.MAX_VALUE)
val numb = randNumb()
val createUser = {
exec(http("Create User")
.post("/users")
.body(StringBody(raw"""{"email": "qa_user_$numb@company.com" }""")))
}
}
val runCreateUsers = scenario("Create Users").exec(Users.createUser)
setUp(
runCreateUsers.inject(constantUsersPerSec(10) during(1 seconds))
).protocols(httpConf)
Where should I be defining my random numbers? 我应该在哪里定义我的随机数? How can I pass it into createUser?
如何将其传递给createUser?
object Users {
val createUser = exec(http("Create User")
.post("/users")
.body(StringBody("""{"email": "qa_user_${numb}@Marqeta.com" }""")))
}
val numbers = Iterator.continually(Map("numb" -> scala.util.Random.nextInt(Int.MaxValue)))
val runCreateUsers = scenario("Create Users")
.feed(numbers)
.exec(Users.createUser)
