外卖平台自动化测试技术原理
基础技术栈

合规的UI自动化测试示例（需平台开放API权限）

from selenium import webdriver
from selenium.webdriver.common.by import By

class DeliveryTestSuite:
def init(self):
self.driver = webdriver.Chrome()

def login(self, username, password):
    """模拟登录流程"""
    self.driver.get("https://merchant.waimai.meituan.com")
    self.driver.find_element(By.ID, "username").send_keys(username)
    self.driver.find_element(By.ID, "password").send_keys(password)
    self.driver.find_element(By.CLASS_NAME, "submit-btn").click()

def order_monitoring(self):
    """订单状态监控（需授权）"""
    while True:
        order_elements = self.driver.find_elements(
            By.CSS_SELECTOR, ".order-item"
        )
        for order in order_elements:
            print(order.text)
        time.sleep(5)

if name == "main":
test = DeliveryTestSuite()
test.login("your_authorized_account", "password")
test.order_monitoring()

合规建议方案

使用官方开放API（如美团配送开放平台）

// 美团配送API调用示例（需申请开发者权限）
public class MeituanApiClient {
private final String appKey;
private final String secret;

public List<Order> getAvailableOrders() {
    // 构造签名参数
    Map<String, String> params = new HashMap<>();
    params.put("timestamp", System.currentTimeMillis());
    params.put("sign", generateSign(params));

    // 发送HTTP请求
    String response = HttpUtil.get(
        "https://openapi.meituan.com/order/list", 
        params
    );
    return parseOrders(response);
}

}

import java.util.concurrent.*;

public class ThreadDemo {
private static final int CORE_POOL_SIZE = 5;

public static void main(String[] args) {
    ExecutorService pool = Executors.newFixedThreadPool(CORE_POOL_SIZE);

    for (int i = 0; i < 10; i++) {
        pool.execute(() -> {
            System.out.println(Thread.currentThread().getName() 
                + " executing task");
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        });
    }
    pool.shutdown();
}

}

threading

class Counter:
def init(self):
self.value = 0
self.lock = threading.Lock()

def increment(self):
    with self.lock:
        self.value += 1

def worker(counter, num):
for _ in range(num):
counter.increment()

if name == "main":
counter = Counter()
threads = [
threading.Thread(target=worker, args=(counter, 100000))
for _ in range(5)
]

for t in threads:
    t.start()
for t in threads:
    t.join()

print("Final counter:", counter.value)
