📂 Leveraging Context Blocks

context blocks group tests under specific conditions or states, improving clarity. Use descriptive context names and nest them to reflect different preconditions or inputs.

RSpec.describe PaymentProcessor do
  context "when the card is valid" do
    let(:card) { Card.new(valid: true) }

    it "processes payment successfully" do
      expect(subject.process(card)).to be_truthy
    end
  end

  context "when the card is expired" do
    let(:card) { Card.new(expired: true) }

    it "raises an expiration error" do
      expect { subject.process(card) }.to raise_error(ExpiredCardError)
    end
  end
end
