导读：我正在尝试为我的bill_total帮助方法创建一个测试. let方法不生成bill1和bill2变量. describe BillsHelper do let(:bill1) { Bill.create(name: 'Bill 1',amount: 1.00) } let(:bill2) { Bill.create(name: 'Bill 2',amount: 1.00) } describe "#bill_total"

我正在尝试为我的bill_total帮助方法创建一个测试. let方法不生成bill1和bill2变量.
describe BillsHelper do
let(:bill1) { Bill.create(name: 'Bill 1',amount: 1.00) }
let(:bill2) { Bill.create(name: 'Bill 2',amount: 1.00) }
describe "#bill_total" do
bill1.amount = 1.00
bill2.amount = 1.00
expect(bills_helper.bill_total).to eq(2.00)
end

解决方法
let语句中定义的名称仅在之前和之后可用,而不是在describe块的外部级别内.如果用它替换内部描述,则可以访问名称.此外,名称实际上不是变量,而是辅助方法.
