In the previous article, we parameterized a test for a Login process with the help of QTP’s Local DataTable. This topic covers the same concept with the help of an (external) Excel file. The process will remain the same, but how we extract data differs.
Parameterization is a process in which parameters, or variables are substituted for hard-coded values which help perform the same operations on the AUT with multiple sets of data. In other words, in QTP, parameterization helps automation developers test an application with different data from a single action (or multiple actions) through multiple iterations.
