transpec古いRSpecをRSpec3の記法に修正[RubyGem]

「transpec」は古い記法で記述されたRSpecをRSpec3に対応した記法に修正してくれるRubyGemです。古いプロジェクトのRSpecをいじる場合にはぜひ活用してください。

🐯 例

変更前

describe Account do
  subject(:account) { Account.new(logger) }
  let(:logger) { mock('logger') }

  describe '#balance' do
    context 'initially' do
      it 'is zero' do
        account.balance.should == 0
      end
    end
  end

  describe '#close' do
    it 'logs an account closed message' do
      logger.should_receive(:account_closed).with(account)
      account.close
    end
  end

  describe '#renew' do
    context 'when the account is not closed' do
      before do
        account.stub(:closed?).and_return(false)
      end

      it 'does not raise error' do
        lambda { account.renew }.should_not raise_error(Account::RenewalError)
      end
    end
  end
end

変更後

describe Account do
  subject(:account) { Account.new(logger) }
  let(:logger) { double('logger') }

  describe '#balance' do
    context 'initially' do
      it 'is zero' do
        # should => expect　に修正
        expect(account.balance).to eq(0)
      end
    end
  end

  describe '#close' do
    it 'logs an account closed message' do
      expect(logger).to receive(:account_closed).with(account)
      account.close
    end
  end

  describe '#renew' do
    context 'when the account is not closed' do
      before do
        # Stubの書き方が修正
        allow(account).to receive(:closed?).and_return(false)
      end

      it 'does not raise error' do
        # エラーチェックの記法が修正
        expect { account.renew }.not_to raise_error
      end
    end
  end
end
