ActionDispatch :: IntegrationTest中的Stubbing方法

Question

我正在做一些条带集成测试,我想存根/模拟几个端点.我试图这样做:

Stripe::Charge.stubs(:retrieve).returns({:balance_transaction => 40})

但我得到以下内容:

NoMethodError: undefined method `stubs' for Stripe::Charge:Class

存根这个的正确语法是什么？Rails 4,Ruby 2.

编辑:这是我的完整测试方法.基本上我的payment_succeeded webhook命中条带以检索费用,并且它是相关的余额交易以记录交易费用.我正在使用stripe_mock来模拟webhook事件,但我宁愿使用标准的存根技术来完成其余部分.请注意,即使我将其更改为"stub",它也会抛出相同的错误(使用stub替换存根).

require 'test_helper'
require 'stripe_mock'

class WebhooksTest < ActionDispatch::IntegrationTest
  # called before every single test
  def setup
    StripeMock.start
  end

  # called after every single test
  def teardown
    StripeMock.stop
  end

  test 'invoice.payment_succeeded' do
    Stripe::Charge.stubs(:retrieve).returns({:balance_transaction => 40})
    event = StripeMock.mock_webhook_event('invoice.payment_succeeded', { :customer => "stripe_customer1", :id => "abc123" })
    post '/stripe-events', id: event.id
    assert_equal "200", response.code
    assert_equal 1, StripeInvoicePayment.count
    assert_equal 'abc123', event.data.object.id
  end
end

Answer 1

在我看来，唯一不正确的是 .stubs ，而它应该是.stub。
