As a programmer, I deal a lot with forms. Build the form, test the form, debug the form, test again, test test and test again.
It is still ok to fill up only 2 to 3 fields forms but it eats up your time if you have to fill up more than 10 fields everytime you want to test a form.
Further more if the form fields are all mandatory!
With the following tools you can just fill up the forms with dummy data or some pre-set data. It maybe useful for other purpose as well. Don’t know.
1. Form Filler
2. JunkFill
