Hi John, since it's a simple predicate, we can test what cases will result true, and what false. E.g. :
(is (false (valid-vector? [])) (is (false (valid-vector? [:a])) (is (false (valid-vector? [1])) (is (true (valid-vector? [:a 1])) Practically, I do feel it's a bit unnecessary to use test.check here. Though, you might find it helpful, say, to generate vector of different kinds to test!? — Sent from Mailbox On Fri, Mar 27, 2015 at 3:14 PM, John Louis Del Rosario <joh...@gmail.com> wrote: > I have a function I want to try out test.check on.
