ruby - ActionDispatch::IntegrationTest 中的 stub 方法

Question

我正在做一些条纹集成测试，我想 stub /模拟一些端点。我正在尝试这样做:

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

但我得到以下信息:

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

stub 的正确语法是什么？ Rails 4、Ruby 2。

编辑:这是我的完整测试方法。本质上，我的 payment_succeeded webhook 命中 strip 以检索费用及其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 stub 技术来 stub 它们的其余部分。请注意，即使我将其更改为“ stub ”，它也会抛出上面相同的错误(用 stub 代替 stub )。

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

这里唯一对我来说不正确的是.stubs，而它应该是.stub。 .
