# 使用requests库进行接口测试
import requests

# 登录接口测试
url = "https://api.example.com/login"
payload = {
    "username": "test_user",
    "password": "test_pass123"
}
headers = {
    "Content-Type": "application/json"
}

response = requests.post(url, json=payload, headers=headers)
assert response.status_code == 200
assert response.json()["code"] == 0
print("登录接口测试通过")

// JMeter BeanShell断言示例
String response = prev.getResponseDataAsString();
if (response.contains("success")) {
    SampleResult.setSuccessful(true);
    SampleResult.setResponseMessage("接口返回成功");
} else {
    SampleResult.setSuccessful(false);
    SampleResult.setResponseMessage("接口返回异常：" + response);
}

测试场景：1000用户并发登录
平均响应时间：2.3秒
95分位响应时间：3.8秒
最大响应时间：5.2秒
TPS（每秒事务数）：435
错误率：0.02%
结论：系统性能达标，建议优化数据库连接池
