assert_predicate(o1, op, msg = nil)

public

For testing with predicates.

assert_predicate str, :empty?

This is really meant for specs and is front-ended by assert_operator:

str.must_be :empty?

# File lib/minitest/unit.rb, line 348
    def assert_predicate o1, op, msg = nil
      msg = message(msg) { "Expected #{mu_pp(o1)} to be #{op}" }
      assert o1.__send__(op), msg
    end
