Trying some things out with Data.define

data_object_spec.rb

RSpec.describe Data do
  subject { data.new(**input) }
  let(:data) { Data.define(:a, :b) }

  context "when providing all arguments" do
    context "with string keys" do
      let(:input) { { "a" => 1, "b" => true } }
      it { is_expected.to have_attributes(a: 1, b: true) }
    end

    context "with symbol keys" do
      let(:input) { { a: 1, b: true } }
      it { is_expected.to have_attributes(a: 1, b: true) }
    end

    context "with mixed keys" do
      let(:input) { { "a" => 1, :b => true } }
      it { is_expected.to have_attributes(a: 1, b: true) }
    end

    context "with nil values" do
      let(:input) { { a: nil, b: nil } }
      it { is_expected.to have_attributes(a: nil, b: nil) }
    end
  end

  context "when providing extra arguments" do
    let(:input) { { a: 1, b: true, c: :sea } }
    it { expect { subject }.to raise_error(ArgumentError) }
  end

  context "when providing too few arguments" do
    let(:input) { { a: 1 } }
    it { expect { subject }.to raise_error(ArgumentError) }
  end
end

rspec output:
