update: nice article parameterized tests in nunit 2.5
http://www.pgs-soft.com/new-features-in-nunit-2-5-part-1-parameterized-tests.html

an alternative bloating unit test, can offload creation of testcasedata using testcasesource attribute.

testcasesource attribute lets define method in class invoked nunit , data created in method passed test case.

this feature available in nunit 2.5 , can learn more here...

[testfixture] public class datevaluestest {     [testcasesource(typeof(datevaluestest), "datevaluesdata")]     public bool monthisdecember(datetime date)     {         var month = date.month;         if (month == 12)             return true;         else             return false;     }      private static ienumerable datevaluesdata()     {         yield return new testcasedata(new datetime(2010, 12, 5)).returns(true);         yield return new testcasedata(new datetime(2010, 12, 1)).returns(true);         yield return new testcasedata(new datetime(2010, 01, 01)).returns(false);         yield return new testcasedata(new datetime(2010, 11, 01)).returns(false);     } }
