背景
- 使用Paymill 的订阅计费功能开发应用程序。
- 利用Ruby 包装器，我创建了一个
PaymentProvider类和规范，如下所示。
问题
如何使测试付款失败？（例如卡被拒绝，或卡在未来的订阅付款中过期）
Stripe 可以让我使用特殊的卡号来执行此操作，但 Paymill 似乎没有任何此类文档（英文）。
payment_provider.rb
class PaymentProvider
Paymill.api_key = ENV['PAYMILL_PRIVATE_KEY']
def self.start_new_subscription(email, description, token)
offer = Paymill::Offer.find(ENV['PAYMILL_OFFER_ID'])
client = Paymill::Client.create(email: email, description: description)
payment = Paymill::Payment.create(token: token, client: client.id)
subscription = Paymill::Subscription.create(client: client.id, offer: offer.id, payment: payment.id)
subscription.id
end
end
payment_provider_spec.rb
require 'spec_helper'
describe PaymentProvider do
describe "#start_new_subscription" do
it "returns a subscription id, starting 'sub_' when successful" do
email = "mike@mike.com"
description = "me"
token = get_payment_token
subscription_id = PaymentProvider.start_new_subscription(email, description, token)
expect(subscription_id[0,4]).to eq('sub_')
end
end
def get_payment_token
# Simulate the JavaScript bridge we would use in production
params = {
'transaction.mode' => 'CONNECTOR_TEST',
'channel.id' => ENV['PAYMILL_PUBLIC_KEY'],
'jsonPFunction' => 'any_string',
'account.number' => '5500000000000004',
'account.expiry.month' => 3.years.from_now.month,
'account.expiry.year' => 3.years.from_now.year,
'account.verification' => '111'
#'presentation.amount3D' => BigDecimal('10.00'),
#'presentation.currency3D' => 'GBP'
}
http = Net::HTTP.new('test-token.paymill.de', 443)
http.use_ssl = true
response = http.get url_query_string(params)
response.body.scan(/tok_\w*\b/).first # Use a regex to pull the token from the (not-quite-JSON) response
end
def url_query_string(hash)
"/?" << URI.escape(hash.collect{|k,v| "#{k}=#{v}"}.join('&'))
end
end
