  default_value_for :name, 'no name'
  default_value_for :age, value: 20, allows_nil: false
end

# spec/models/user.rb
describe User, type: :model do
  # name
  it { is_expected.to have_default_value_for(:name) }
  it { is_expected.to have_default_value_for(:name).with_value('no name') }
  it { is_expected.to have_default_value_for(:name).with_value('no name').and_allow_nil }

  # age
  it { is_expected.to have_default_value_for(:age) }
  it { is_expected.to have_default_value_for(:age).with_value(20) }
  it { is_expected.to have_default_value_for(:age).with_value(20).and_disallow_nil }
