compare response time

Gatling (Open-Source)
1

Hi ,

I 'm quite new to gatling (version = 2.2.2) / scala but looks like a great tool so far.

For one of my cases I would like to have an additional assertion in which I compare mean response time of 2 scenarios/groups of requests.

The idea is to check that mean response time of GET_detailsBatch (1 request to get details of 50 items) is always less than mean response time of GET_DetailsOneByOne (50 requests to get details of 1 item)

How can this be achieved?

setUp(
  GetDetailsBatch.inject(atOnceUsers(1)),
  GetDetailsOneByOne.inject(atOnceUsers(1))
).protocols(httpProtocol)
  .assertions(details("GET_DetailsBatch").responseTime.mean.lessThan(40))

  .assertions(details("GET_DetailssOneByOne").responseTime.mean.lessThan(50))
