代理技术是SilkTest 产品架构中非常独特的一部分。 它是一段简洁的程序，可以最准确的模拟最终用户如何来运行该应用。代理可以被部署到多台计算机上并接受SilkTest 主组件的控制。 它可以提供详细到对一个分布式事务处理的通过/失败的测试。SilkTest优于简单的方案验证－也就是对复杂的，实际情况或分布式处理的测试能力－正是通过代理技术来实现的。

The Agent is the software process that translates the commands in your 4Test scripts into GUI-specific commands. In other words, it is the Agent that actually drives and monitors the application you are testing. One Agent can run locally on the host machine. In a networked environment, any number of Agents can run on remote machines.
