There's less functionality to test if you've described your business constraints in concise type declarations. The type contract is short enough to be validated at a glance.

I'm having a hard time imagining a situation in which static typing could replace even one single test, let alone it being a common occurence. In any such case I can come up with, the test is needlessly limited in scope and can be replaced by a much more comprehensive test. What specifically did you have in mind?
