并发测试工具seige使用介绍

需求

抽奖每天每个用户只能抽3次 需要验证高并发情况下同一用户是否存在超抽 即抽奖次数超过3次

# 模拟同一用户并发提交10次抽奖请求
siege 'http://localhost:8080/lottery/draw/ POST userId=foo'  -r 1 -c 10 -b

需求

同一用户同时进行兑奖和抽奖操作 可能会有数据紊乱的情况 如当前红包总额20元， 这时同时进行兑奖和抽奖操作， 假如抽奖中了10元， 那么最终结果可能会有如下的几种情形

正常情况 兑了一个20元的优惠券， 红包总额为10元
异常情况一 兑了一个20元的优惠券 但红包总额为30元
异常情况二 兑了一个20元的优惠券 但红包总额为0

使用siege验证上述情况

# 准备接口url文件
cat test_urls
http://localhost:8080/lottery/draw/ POST userId=foo #抽奖
http://localhost:8080/lottery/redeem/ POST userId=foo #兑换

#并发提交上述两个接口
siege -r 1 -c 2 -f test_urls -b
