Nunit test design

Question

I'm designing tests via selenium for the first time.

 

My testing is against a web application, logging in, filling out data, confirming and submitting etc.

 

Is it better to have a long script (NUnit test method) with multiple asserts or console messages; 

 

Or is it better to have multiple tests each logging into the application and flowing through the same process checking and stopping at different points?
