In web based applications doing manually parametrization is 
very very difficult parametrization is nothing but testing 
one content of your application with many examples and it 
is a repeated process so it is very difficult to do manually

Hi,
wn ever we need to test the application functionaltiy with 
the different input values we can go through the 
parametrization concept.
for eg u have to validate the different users.using 
username and password.(for all functionaliy is same)
then u can write all the values of users in datatable and 
using data driver wizard u can test easily.
but manually it will take too much time.

Parameterization= When you are testing your application You
may want to check how it performs the same operation with
different sets of data at that point of time we go for
parameterization example if you have a login name and
password you may want to test how the test behave with
different login names and password then you need to
parameterize the test.
You can do manual parameterization and data driven
parameterization ...Usually manual parameterization is done
when there is less data and we do data driven
parameterization is done in automated testing when we need
to test lots of data.

For manualparametrisation you need to wite the Vb script
manually
see the script for flight login application

datatable.AddSheet "sree"
datatable.ImportSheet "abc.xls,sheet1,sree"
k=datatable.GetSheet("sree").getrowcount
For i=1 to k
SystemUtil.Run "C:\Program Files\Mercury
Interactive\QuickTest
Professional\samples\flight\app\flight4a.exe"
Dialog("Login").WinEdit("Agent Name:").Set datatable
("name","sree")
Dialog("Login").WinEdit("Agent Name:").Type  micTab 
Dialog("Login").WinEdit("Password:").SetSecure
datatable("pwd","sree")
Dialog("Login").WinButton("OK").Click
Next



for datadriver there are two ways
1.Tools->Data driver->Parametrise (in parametrise dialog you
can parametrise selected objects)

2.Go to keyword view
  just there is a icon located at the corner of each object
just click on that icon there is a option like parametrize
by using tht option u can parametrise by using data driver.
