Refactor-safely examples

1) Characterization test for a presenter

RSpec.describe OrderPresenter do
  it 'formats totals as currency' do
    order = build_stubbed(:order, total_cents: 12345)
    expect(OrderPresenter.new(order).formatted_total).to eq('$123.45')
  end
end

2) Safe extract example

Before:

def index
  @rows = expensive_query.map { |r| transform(r) }
end

After (extract):

def index
  @rows = Presentation::RowsBuilder.build(expensive_query)
end

3) Rollback plan

  • If tests fail after refactor, revert commit, examine failing characterization tests, and extract smaller unit of work.
