What is parameterization

Parameterization is replacing the original value with a parameter and the value has to be in the database.

Ø Record www.Walmart.com .
Ø Go to the “zip code” box and type a valid zip code.
Ø Click “find”. Then “Stop”.
To Parameterize:
Ø Click on “Tool”
Ø Click on “Data driver”
Ø Click on “Parameterize”
Ø Click on “Data driver wizard”
Ø Click on “Step by step parameterization”
Ø Click on “Next”
Ø Click on “Parameter name”
Ø Change the parameter [08648] by highlighting and then replacing with “zipcode”.
Ø Click “OK”
Ø Click “Finish
Ø In Data driver, - click “OK”.
An Excel sheet opens up with “zipcode” on top row.
Ø Fill in other valid zip codes and an invalid zip code. If the zip codes start with “0” then:
Ø Highlight the cell
Ø Right click
Ø Highlight “Format”
Ø Click on “Custom No:” delete the “General” and type 5 zeros.
Ø Click “OK”
Ø Go to “Test”
Ø Click on “Settings”
Ø Click on “Run”
Ø In “Test settings” choose “Run from all rows”
Ø Click “OK”
Then run from the top. When we run from all rows it gives us as many results as the number of zip codes. For the invalid zip code there would be no sight and it should say “Please enter a valid zip code”.
If we want to watch the pages closely we can put wait statement right in front of the “Start transaction” after the comment. E.g. wait (time).

Multiple Parameterizations

Let us take the example: www.Greyhound.com> anywhere> US.
Then we fill up the form with starting city, destination, time, number of adults, children, seniors etc. After we fill up the form and run. We must parameterize every single area. For example:
1) Start city
2) End city
3) Start month
4) Start day
5) Start time
6) Adults
7) Children
8) Seniors
All the values that we choose must be in the database in the exact same way we use it to give parameter. After we do that we run it the same way. Since we parameterize multiple values it is called multiple parameterizations.
