🔍 Use expect Syntax for Assertions​

RSpec’s expect syntax is readable and intuitive. Wrap your target call in expect(...) and chain matcher methods like to eq or to be_truthy to assert behavior.

# spec/string_spec.rb
describe String do
  it 'returns uppercase version' do
    expect('hello'.upcase).to eq('HELLO')
  end

  it 'is empty when initialized without arguments' do
    expect(String.new.empty?).to be_truthy
  end
end
