what is meant by "Parameterization technique"?

Answer Posted / nilanjan saha

Parameterization technique helps us to replace the constant
values with variables(or socalled

parameter) to increse the flexibility of the test.
Suppose for testing purpose of the Login Id and Password
field your Test Case is to "Verify for

alphanumeric values "
So here your Test data should be say
1)id-Nilanjan
Pwd-mercury
2) Nilanjan100
Mercury
3)10000
MERCURY

So manually you can pass the data for 3 time and check,But
in parameterrization concept load all

these 3 set of data in dataTable , QTP automatically fetch
tha data from that DataTable Exacel

sheet one by one those Id & pwd pair.And the run time it
will also show you the Row1,Row2,Row3.

The test will go for 3 iterations and accordingly Test
result will be generated.
