its(:to_s) fails with got: "to_s"

[TylerRick]

This appears to be a bug. I would expect this example to pass but it doesn't:

describe 1 do
  # fails with got: "to_s"
  its(:to_s) { should == 1 }
end

Please post the full error message.

Actually, please run with --backtrace and then post the full failure/error message. Thx.

This is working for me in 2.11. Full backtrace will help.

its supports classes only, but you're supplying instances (1 and '1') to describe. The fact that it works sometimes is an accident. You could argue it should work w/ instances, which is a fine argument, however we're going to remove its from rspec-3 (extract to its own gem) so we're not going to do anything to change its behavior now.

As for the issue related to named_subject, that method provides a name you can use to access the subject, but its changes the value of subject. I'm on the fence about making it work any differently in order to support its, but I'm willing to discuss it. If you want to, please open a separate issue (since it is a separate issue).

BTW - thank you for providing clear examples of the problem.
