如何使用早該匹配器來測試日期驗證

Question

我驗證日期字段如下：

驗證：RETURN_DATE，包含：{在：（Date.today + 1.day..Date.today + 4.weeks ）}

我測試它使用Rspec的語法如下：

it "should only accept return date that is later than the current date" do 
    quotation_request = FactoryGirl.build(:quotation_request, return_date: Date.today) 
    expect(quotation_request.valid?).to be_falsy 
end 

在報價請求模型驗證：

validates :return_date, inclusion: {in:(Date.today+1.day..Date.today+4.weeks) 

這可以工作。我想知道是否有一種方法可以使用Shoulda匹配器來測試，如果有的話，以及如何做到這一點？

Answer 1

首先，你應該使用一個進程的日期

validates :return_date, inclusion: { in: ->(model) { (Date.today+1.day)..(Date.today+4.weeks) } } 

然後馮·可以調整到某一領域的評估，看看當它是假的，真正的

# Set the expectation that the factory is setup correctly 
expect(quotation_request).to be_valid 

# Then check that values "just" out of range make it invalid 
quotation_request.return_date = Date.today 
expect(quotation_request).not_to be_valid 

quotation_request.return_date = Date.today+4.weeks+1.day 
expect(quotation_request).not_to be_valid
