Question { Wipro, 6626 }

1>why parameterization is necessary in qtp?
2>if we give constant value then what problem?

Answer

if we give constant value.it can validate the test for one
input value only.by testing the testcase with simply single
input value we cannot pass testcase.
mainly we go for qtp is to test the application with more
no of inputs.
qtp has feature data-driven testing.by parameterization we
can test the 1 testcase with more num of inputs for
accurate results.
