RSpec中意外的nil变量 [英] Unexpected nil variable in RSpec

问题描述

我有一个非常基本的RSpec示例，该示例不起作用。这是代码：

I have a very basic RSpec example that doesn't work. Here's the code:

require 'spec_helper'

describe "Referral-type functionality" do
  describe "Affiliate system" do
    before { @affiliate = Affiliate.create(account_id: 1) }
    subject { @affiliate }

    describe "URL should work" do
      visit @affiliate.aff_url
    end

  end
end

但是，当我运行它时，rspec给出了NoMethodError，因为@affiliate为零。我缺少什么？

When I run it, though, rspec gives a NoMethodError because @affiliate is nil. What am I missing?

推荐答案

在之前中定义的实例变量块在示例块中可见（它，指定），但在 describe <中不可见/ code>块。例如：

The instance variables defined in the before block are visible in the example block (it, specify) but not in the describe block. E.g.:

specify 'URL should work' do
  visit @affiliate.aff_url
end
