本指南帶你跑出第一支 LoadDensity 壓測。

User 類型

LoadDensity 提供六種 user 類型：

  • fast_http_user — 高吞吐 HTTP（locust.FastHttpUser + geventhttpclient）。

  • http_user — locust.HttpUser + requests。

  • websocket_user、grpc_user、mqtt_user、socket_user — 詳見第 4 章。

以 Python API 執行

from je_load_density import start_test

start_test(
    user_detail_dict={"user": "fast_http_user"},
    user_count=50,
    spawn_rate=10,
    test_time=30,
    variables={"base": "https://httpbin.org"},
    tasks=[
        {"method": "get",  "request_url": "${var.base}/get"},
        {"method": "post", "request_url": "${var.base}/post",
         "json": {"hello": "world"},
         "assertions": [{"type": "status_code", "value": 200}]},
    ],
)

啟動 Locust Web UI

start_test(
    user_detail_dict={"user": "fast_http_user"},
    user_count=50, spawn_rate=10, test_time=30,
    web_ui_dict={"host": "127.0.0.1", "port": 8089},
    tasks=[{"method": "get", "request_url": "https://httpbin.org/get"}],
)

之後在瀏覽器開啟 http://127.0.0.1:8089。

以 JSON 動作腳本執行

建立 test_scenario.json：

{"load_density": [
  ["LD_start_test", {
    "user_detail_dict": {"user": "fast_http_user"},
    "user_count": 20, "spawn_rate": 10, "test_time": 30,
    "tasks": [{"method": "get", "request_url": "https://httpbin.org/get"}]
  }],
  ["LD_generate_summary_report", {"report_name": "smoke"}]
]}

執行:

python -m je_load_density run test_scenario.json

或於 Python：

from je_load_density import execute_action, read_action_json
execute_action(read_action_json("test_scenario.json"))
