Microsoft Velocity Test

          这两天对即将发布的产品做了个Velocity Test，其定位应该属于兼容性测试。测试的过程倒是比较简单，装上相应微软提供的工具，做好一些前期的准备工作，直接运行就行了，中间几乎无需人为介入，只是考机非常耗费时间，整个测试过程大概需要花费3至4个小时左右。测试结束，对Velocity Testing做个简单的总结。

 

一．       什么是 Velocity Testing?

引用一下微软在Velocity Test Suit介绍文档中提及的概念：

It provides guidelines for original equipment manufacturers (OEMs) to precisely measure (as well as baseline) OS performance, and quality of manufacturing images, based on the following criteria:

1.    Device Compatibility

2.    Application Compatibility

3.    Performance (Responsiveness, boot time, sleep/hibernate/resume time etc)

4.    Power Management

上述概述中precisely一词很好的定位了此测试的精度性，从而可以肯定的是Velocity测试的进行还是极具有参考意义的。

 

二．       Velocity Testing到底测试些什么？

该测试主要关注三个方面：Performance、Reliability、Security，细分如下：

 

 1.    Performance

Criteria

Test

Note

Performance

Boot Complete

Important determinant of user experience

Shutdown

How fast machine goes off - Important determinant of user experience

Suspend

How fast machine goes into sleep - Important determinant of user experience

Resume

How fast machine resumes from sleep - Important determinant of user experience

IE Launch Time

How fast until I can surf the web – Time to warm launch of IE to a blank page

Disk Flush Check

Test for a common hard disk performance issues

 

2.    Reliability

Criteria

Test

Notes

 

Reliability

Driver Verifier Check

Verify correct driver implementation and behavior. Common source of reliability problems

 

Driver Signature Check

Unsigned drivers can adversely impact boot time. Signatures are a logo requirement

 

Driver Update Check

Tests for latest drivers on system except where latest version has significant quality issues or was released too close to image lock to allow good-faith effort to include update

  

Pre-Installs Check

Tests for latest software on system except where latest version has significant quality issues, or was released too close to image lock to allow good-faith effort to include update

 

Compatibility Check

Checks for Windows Vista compatibility of all pre-installs

 

Check for BIOS String or other marker

Necessary to check systems accurately via OCA

 

 

3.    Security

Criteria

Test

Notes

 

Security

Service Pack  and Security Update Check

Latest service pack installed on

  

Firewall Enabled

Checks for Windows firewall (or other replacement) enabled after OOBE and enabled after OOBE

  

UAC Enabled

Checks for User Account Control feature enabled after OOBE

 

Defender Enabled

Windows Defender (or replacement) enabled after OOBE

 

Security Integrity Check

Checklist of 6 manual tests to help assure safe usage experience

 

 

三．       Velocity Testing的使用场合

1.    PC的OEM厂商，如DELL、HP、Lenovo在发布产品前对整个系统（包含硬件和软件）做的Velocity测试，以调优。

2.    软件公司可进行两次Velocity测试，一次是未安装发行软件，一次是安装了发行软件，对比两次测试结果，从而来考核发布软件对目标机器是否存在性能上的显著影响。这一点更趋向于兼容性测试范畴。

3.    个人用户如果购置了新机后也可进行该测试，可以有效检验机器性能是否能达到了微软的要求，以此验证PC厂商有没有忽悠目标用户。

 

四．       微软的其他同类测试

除了Velocity Testing，微软还提供了另外两种类似的测试种类Logo Testing、OEM Ready Testing，具体的区别参看下图：

 

     

 

五．       其它

在Velocity测试开展前，要进行一些相应的准备工作，在测试过程中可能还要处理蓝屏异常，等等相关操作可参考微软提供的文档“Velocity_Test_Suite_Standalone_Edition_v4.xps”。

另外微软官网上有一份主题是“The Vista Velocity Program“的PPT，很详细的描述了该测试的技术细节，以及其他相关类似测试的对比，可点击这个链接进行下载！
