Test Case

The example test case from the presentation, see below to run it.

// System under Test – the target system you'll generate traffic against
definition.setTarget("testapp.loadtest.party");

// your Load Generator Cluster
definition.setTestOptions({
cluster: { sizing: "preflight", },
});

// user base of 10.000 unique users
// doing a user journey
// in highest hour in a week
var $userBase = 10000;

var $newUserPerSecond = $userBase / 60 / 60;

definition.setArrivalPhases([
// for 5 minutes
// start RATE new clients/users per second
{ duration: 5 * 60, rate: $newUserPerSecond }, // 100%

{ duration: 5 * 60, rate: $newUserPerSecond * 2 }, // 200%
{ duration: 5 * 60, rate: $newUserPerSecond * 3 }, // 300%
{ duration: 5 * 60, rate: $newUserPerSecond * 4 }, // 200%
]);

// the user Journey
definition.session("flower-shop-user-journey", function(session) {
session.get("/flowers", {
tag: "flower-list"
});

session.wait(30); // wait for 30 seconds

var flower = session.ds.generate("random_number", { range: [1000, 9999]});
session.get("/flowers/:flowerId", {
tag: "flower-detail",
params: {
flowerId: flower
}
});

session.wait(30); // wait for 30 seconds

session.post("/flower-cart/add", {
tag: "add-flower-to-cart",
payload: JSON.stringify({
"item": {
"qty": session.ds.generate("random_number", { range: [1, 9]}),
"flower_id": flower
}
})
});
});
