  LoadStrikeScenario,
  LoadStrikeSimulation,
  LoadStrikeStep
} from "@loadstrike/loadstrike-sdk";

const scenario = LoadStrikeScenario
  .create("orders", async (context) => {
    return LoadStrikeStep.run(
      "publish-order",
      context,
      async () => LoadStrikeResponse.ok("200")
    );
  })
  .withLoadSimulations(LoadStrikeSimulation.inject(10, 1, 20));

const result = await LoadStrikeRunner
  .registerScenarios(scenario)
  .withRunnerKey("rkl_your_runner_key")
  .run();

A valid RunnerKey is required to execute live workloads.
