@dgorodnichy @Maychell Oh, derp -- this is only available on the master branch, this isn't in a release just yet.

@dgorodnichy Hmm, that's definitely very strange. Are you sure you're using 3.1.2? Where is describe coming from if you're using Minitest -- are you using Minitest::Spec?

@mcmire, Yes, I use Minitest::Spec. I'm sure that shoulda-matchers version is 3.1.2

Same thing here.
My class:

class User
  belongs_to :address, optional: true
end

Test:

RSpec.describe User, type: :model do
  context 'associations' do
    it { is_expected.to belong_to(:address).optional }
  end
end

Result:

1) User associations
     Failure/Error: it { is_expected.to belong_to(:address).optional }

     NoMethodError:
