Start with 10 user and add every 5 min 50 user gatling scala

Question

I am beginner in GATLING. I want to execute performance scenarios with below expectations:

Start with 10 user and add every 5 min 50 user. This means:

• 0 min: 10 user (at once)
• 5 - 10 min: 60 user
• 10 - 15 min: 110 user
• 15 - 20 min: 160 user

below is my simulation setup:

setUp(Scenarios.inject(
    nothingFor(5 seconds),
    atOnceUsers(Environment.atOnceusersCount.toInt),
    rampUsers(Environment.rampUsersCount.toInt) during (Environment.durationForRampusers.toInt seconds)

  )

where rampUsersCount = 2
durationForRampusers = 10 seconds

I want to understand how to increase rampUsers count gradually.

Answer 1

Use either incrementUsersPerSec or incrementConcurrentUsers , depending on if you want an open or closed workload model, see official documentation .
