My workaround for the moment is using a singleton method:

1.9.3-p194 :001 > require 'minitest/mock'
1.9.3-p194 :002 > obj = MiniTest::Mock.new
1.9.3-p194 :003 > obj.expect(:size, 5)
1.9.3-p194 :004 > def obj.to_s; 'an object'; end
1.9.3-p194 :005 > obj.size
   => 5
1.9.3-p194 :006 > obj.to_s
   => "an object"
