各部分的 STAX 脚本代码示例如下：
示例代码 1. 转换虚机状态

<request>'DELAY %s' % (delayTime)</request>
</stafcmd>
<sequence>
<else>
<log level="'user1'">'%s is opened' % (vmIP)</log>
</else>
</if>
</sequence>
</loop>
</sequence>
</timer>
<!-- If the target did not ping within the given amount of time -->
<if expr="RC != 0">
<throw exception="'eTerminateFunction'">
'The target failed to reboot and start STAF within the specified amount of time.
Please check the target for further details'
</throw>
</if>
</sequence>
通过在 VMware 服务器上执行 VMware 软件本身提供的转换 snapshot 的命令，可以方便的将目标虚拟机恢复到测试的初始状态。继而，可以通过 STAF 提供的 PING 服务进一步确认目标虚拟机已经开启，并且运行在其上的 STAF 也工作正常。一旦确认目标机工作正常，便可以开始后续的测试工作，否则需输出出错提示，并且返回。
