Thread: need to verify results by picking each value from dropdown

I have to pick values from 2 dropdowns and verify the results, i.e., Ex. i have state dropdown and city dropdown, i have to verify that if user selects Maharashtra(State) & Pune(City) & clicks search the system should display all the MBA colleges in Pune city.

I have to write function where in -

1. I need to pass the arguments 1 -by - 1 into both of the dropdown and verify results OR
2. I select each values from each dropdown and click search button everytime and verify results that the list displayed is for Pune MBA colleges

Also, the next time i have to change the state i.e., Andhra Pradesh & City - Hyderabad,thenVaizag,Warangal
Then karnataka - Bangalore, then Mangalore, then Mysore and so on so forth...
