l a clean systemand how long it might take
if you minimize the setup timeby using an automated and enhanced preparation process. Alot of effort can be saved here, depending on the number ofsetups required for your test plan. To see the possible timesavings, estimate how many times you will need a clean platform
installed to perform all testpasses on it. The basic formula
for the time that you’ll need is “buildcount” multiplied
by “langcount” multiplied by “testercount,” where “buildcount”
is the number of builds produced during the project,
“langcount” is the number of languages that exist for these
builds and “testercount” is the number of test engineers
working on the project. You will need to multiply this result
by the number of any specific configurations within your testing
matrix (such as a file system or browser). The higher
number you get, the more it pays to use a well-prepared disk
image setup process. Based on your “setup” activity estimates,
you can allocate the appropriate time required for the preparation
of disk images. To give you an idea, it typically takes an
hour to install and configure Windows XP, while loading and
adjusting a disk image takes only 10 minutes.
Platform specifics — image properties. Each platform has
its own specifics that are worth tracking and need to be identified
before saving the disk image. Windows is a fairly wellknown
platform, so let’s take a look at what is good to track
on Linux:
FileSystem: Ext2 and so on
Kernel build: 2.2.1.3
Distribution: Mandrake, Red Hat, SuSE, Debian and so on
PC Type: GX260, GX270
Language: Core language (English, French, Czech)
Regional settings: English, French, Czech
Created by: person who installed the system
Version and type
of Web browser:
Mozilla, Netscape

for other users on aserver. It is wise toimplement an image
naming convention thatis unique, easy to readand consistent. Using an
automated image propertiesreading tool togetherwith a Web-based interfacefor tracking imagesfor multiple platforms
can prove to be very useful,as the Web tracking interface can be displayed from anyplatform (if designed properly). The graphic “Image propertiesfor a Dell GX260 Tablet PC” provides an example of image
properties for a Tablet PC using QASight’s Clean OS imagetracking application.Test on appropriate browsers. Which browser support to
cover across platforms is an important question that shouldbe answered in your test plan. Each platform tends to have its
“flagship” browsers — for example, Mozilla or Netscape on
Linux and Mac, Internet Explorer for Windows. Make sure
you identify browser versions and locales for testing. And, ofcourse, in Web application testing, the browser is actually part
of the testing platform.Setting up older operating systems on new hardware.
Sometimes, you will be asked to test on an older platform
such as Windows 98 SE or Mac OS 9. It may be hard to configure
your latest hardware with an old system when drivers
don’t exist for it. The best advice here is to use the hardware
manufacturer’s Web site to download the latest drivers. (Tip:
