        Answer - 
        
To iterate through options in test script you can loop features of the programming language, for example to type different test data in a text box you can use “for” loop in Java
// test data collection in an array
String[ ] testData = { “test1” , “test2” , “test3” } ;
// iterate through each test data
For  (string s: test data) { selenium.type ( “elementLocator”, testData) ; }
