I am new to asp, C#,nunit. I am trying to write (do my homework/assignment) nunit testcases for a simple web form, that doesn't have any business logic.

The web form has 4 text boxes (Name, emailaddress, password, phone number)
, a radio list , drop down list (gender). The form just validates the data and shows the data in an other page as output text (labels).
Validation is just regEx validation for email, phone. length validation for name and pwd.
requiredField validation for gender.

Please suggest how do I write NUnit test case for this web form

Example, if there a method that calculates a factorial, I call the method first with a parameter **given in code** (ex: 4). It returns me 4! into a variable 'result' (that is result has 24 now). 
Then I will call AssertEquals(24,result)

So, in case of web form, which expects input from user. input is not given in the code.
What will be the parameters of AssertEquals

Thanks,
