# test命令

#### 命令功能

使用指定轮次的参数再次进行测试。


#### 命令格式

```
test [-h] <n1,n2,...> <n> test round n1,n2,... and test <n> times
```

可指定对应轮次的复测次数，如使用自动调优中第一轮的参数复测5次：test 1 5。


#### 使用示例

对第一轮复测两次。

```
test 1 2
```

返回信息如下：

在使用参数赋值前，为确定调优参数是否稳定，可对性能提升较好的轮次进行多次复测，结果中 变异系数 “CV(%)”越小，则表明复测的性能数据一致性越高，对应轮次的调优参数越稳定。

合理的测试场景下，变异系数“CV(%)”低于1%认为参数对应优化的效果非常稳定，1% - 5%是比较稳定，5% - 10%不太稳定可根据实际情况是否接受，若超过10%则认为此轮的参数不稳定，建议优先解决性能数据的稳定性问题（环境或人为因素）。

在一般情况下，使用AB轮的方式进行复测，来保证测试结果的稳定性。例如：需要对最高性能轮次（假设轮次号为A）的结果进行复测，可以使用test 0,A 5，对基线轮次和最高性能轮次交替测试5组，共10次。
