Pause:

  Fixed pause duration:
    pause(duration: Duration)
  Random pause duration:
    pause(min: Duration, max: Duration)
  Example:
    .exec(http("get some page").get("/some.php")).pause(1 seconds, 10 seconds)

Checks:

  Default is checking for 200 status
  example of expecting 404
    .exec(http("get some page").get("/some.php")).check(status.is(404))
  Multiple checks:
    .check(status.not(400), status.not(404), status.not(500))

Scenario & Simulation

  Creating Scenario:
    val user1 = scenario("gatling 1").exec(http("get some page").get("/some.php"))
    val user2 = scenario("gatling 2").exec(http("get another page").get("/another.php"))
  Apply Scenario to a simulation
    setUp(user1.inject(atOnceUsers(10)),
          user2.inject(atOnceUsers(25))).protocols(httpProtocol)

Inject:
    2 scenarios , first is running all users at once, seconds is ramping up users starting with 100 and going up to 500 in 1 minute.
      setUp(scn.inject(atOnceUsers(10)), otherScn.inject(rampUsersPerSec(100) to(500) during(1 minutes) randomized))

Feeders:
    create a feeder:
    	val random = new util.Random
	    val feeder = Iterator.continually(Map("randomString" -> random.nextString(20)))
	  use it in a scenario:
	    	val scn = scenario("some scenario")
				.feed(feeder)
				.exec(http("some request")
				.post("/nimrod.php")
				.formParam("someParam", "${randomString}")
