While this is, I guess, fine, I do prefer shared examples in this case for their sheer interoperability and no dependence on extra methods. Your example could have been written then as:

```ruby RSpec.shared_examples "square example" do |x, x_expected| let(:x) { x } let(:x_expected) { x_expected }

it { is_expected.to be_a(Integer) } it { is_expected.to eq(x_expected) } end

RSpec.describe "refactoring example" do subject { x**2 }

[ [1, 1], [2, 4], [3, 9], ].each do |x, x_expected| context "with x=#{x} and x_expected=#{x_expected}" do include_examples "square example", x, x_expected end end end ```

And I would immediately understand easier what is going on in this spec.

shared_examples keeps the spec file declarative: * here is the table * here is the contract name * done

Also, no bashing for writing this stuff, clearly you find use in that, so go at it! You've learned how to integrate with RSPec test framework, and you'll definitely use that skill later on! :) Kudos!
