推荐答案
可以使用Symfony提供的Process组件:http://symfony.com/doc/current/components/process.html
You can use the Process component provided by Symfony: http://symfony.com/doc/current/components/process.html
该组件由 Laravel 自己使用，因此您不需要单独通过 composer 安装它.只需将 use SymfonyComponentProcessProcess; 添加到您的文件中.
The component is used by Laravel itself, so your don't need to install it via composer separately. Just add use SymfonyComponentProcessProcess; to your file.
如果您使用它(而不是 php 的 exec() 函数)，您将能够对调用 shell 命令的代码进行单元测试.
If you use it(instead of php's exec() function), you'll be able to unit test the code that calls shell commands.
