DUnit: Advanced unit testing toolkit.

Same hint as for specd: have a look at 'assertOp'!
http://d.puremagic.com/issues/show_bug.cgi?id=4653

alias assertOp!">" assertGreaterThan;
alias assertOp!">=" assertGreaterThanOrEqual;
alias assertOp!"<" assertLessThan;
alias assertOp!"<=" assertLessThanOrEqual;

avoids duplicate code.

Maybe, you can do the same for 'assertStartsWith' and 
'assertEndsWith'?
