我正在做一些条带集成测试,我想存根/模拟一些端点。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
用于存根的正确语法是什么? 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及其相关的余额交易以记录交易费用。我使用stripe_mock来模拟webhook事件,但我宁愿使用标准的存根技术将其余事件删除。请注意,即使我将其更改为' stub'它会抛出相同的错误(使用存根替换存根)。
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

这里唯一看起来不正确的是.stubs应该是.stub。

由于您没有使用RSpec,我建议您安装mocha gem以获得完整的模拟和存根工具选择。这是一个快速入门:
# Gemfile
gem "mocha", :group => :test
# test/test_helper.rb
require "mocha/mini_test"
现在你可以像这样存根:
Stripe::Charge.stubs(:retrieve => {:balance_transaction => 40})
或者,如果你想验证方法是否实际被调用,你可以设置一个期望:
Stripe::Charge.expects(:retrieve)
.with(:id => "abc123")
.returns({:balance_transaction => 40})
