系统质量属性测试：验证非功能性需求
使用
Apache Benchmark
进行基本的性能测试
Apache Bench ab
工具是一个非常易于使用的性能基准测试工具。它是一个命令行（
CLI
）
工具，通过向指定
URL
生成大量的请求，然后将相关的性能指标返回给终端。虽然它
不是很灵活，但是当你需要快速进行性能测试时，它是一个非常不错的工具。你可以
通过包管理器来安装这个工具。如果你使用的是
Windows
，可以通过
Chocolately
安装
SuperBenchmarker
作为替代（
https://github.com/aliostad/SuperBenchmarke
r
）。安装完后，
你只需在终端输入
ab
即可查看可用的参数列表。最常用的
-n
参数用来指定基准测试会
话要执行的请求数，
-c
参数表示可执行的并发请求数，以及目标的
URL
。例如，如果
你要对
Google
进行一次性能测试，一共执行
10
次请求，每次执行
2
个，可以运行示例
12-8
所示的命令。
示例12-8：使用Apache Bench ab对Google进行一次性能基准测试
$ ab -n 10 -c 2 http://www.google.com/
