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  SIEGE 4.0.2  Preparing 10 concurrent users for battle.The server is now under siege...HTTP/1.1 200     0.39 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.39 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.40 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.40 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.40 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.40 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.40 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.41 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.41 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/HTTP/1.1 200     0.41 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/Transactions:                  10 hitsAvailability:              100.00 %Elapsed time:                0.41 secsData transferred:            0.00 MBResponse time:                0.40 secsTransaction rate:           24.39 trans/secThroughput:                0.00 MB/secConcurrency:                9.78Successful transactions:          10Failed transactions:               0Longest transaction:            0.41Shortest transaction:            0.39

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_urlshttp://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  SIEGE 4.0.2  Preparing 2 concurrent users for battle.The server is now under siege...HTTP/1.1 200     0.08 secs:      51 bytes ==> POST http://localhost:8080/lottery/redeem/HTTP/1.1 200     0.12 secs:     122 bytes ==> POST http://localhost:8080/lottery/draw/Transactions:                  2 hitsAvailability:             100.00 %Elapsed time:               0.12 secsData transferred:           0.00 MBResponse time:              0.10 secsTransaction rate:          16.67 trans/secThroughput:             0.00 MB/secConcurrency:                1.67Successful transactions:           2Failed transactions:               0Longest transaction:            0.12Shortest transaction:           0.08
