まず、Rails でテストを作成することに関しては、私は初心者です。[前もって] お待ちいただきありがとうございます。

これが私のクラスです：

require 'json'

class Webhook
  attr_accessor :customer_id, :response, :event_type

  ACCEPTED_EVENTS = ["customer.subscription.deleted", "invoice.payment_succeeded", "invoice.payment_failed"]

  def initialize(json = nil)
    if json
      @response = JSON.parse(json, symbolize_names: true)
      @customer_id = @response[:data][:object][:customer]
      @event_type = @response[:type]
      @user = User.find_by_customer_id(@customer_id)
    end
  end

  def event_accepted?
    true if ACCEPTED_EVENTS.include?(@event_type)
  end

  def process
    return unless event_accepted?

    case @event_type
    when "invoice.payment_succeeded"
      begin
        invoice = Stripe::Invoice.retrieve(@response[:data][:object][:id])
        InvoiceMailer.payment_succeeded_email(@user, invoice).deliver if invoice.amount_due > 0
      rescue => e
        Rails.logger.info "An error as occurred! #{e}"
      end
    when "customer.subscription.deleted"
      @user.expire! if @user
    when "invoice.payment_failed"
      InvoiceMailer.payment_failed_email(@user).deliver
    end
  end
end

これまでの私のテストは次のとおりです。

require 'spec_helper'

describe Webhook do

  describe "instance methods" do
    let(:webhook) { Webhook.new }

    describe "#event_accepted?" do
      it "returns true with a correct event_type" do
        webhook.event_type = "customer.subscription.deleted"
        webhook.event_accepted?.should be_true
      end

      it "returns false with an incorrect event_type" do
        webhook.event_type = "foobar123"
        webhook.event_accepted?.should be_false
      end
    end
  end
end

#processメソッドのテストを書こうとすると、少し戸惑います。どんな助けでも大歓迎です！

プロセス メソッドをテストするには、7 つの異なるパスがあります。私は 2 つのシナリオのテストを書いており、残りはあなたが試すために残しています。また、私のテストは、他のメソッドのプロセス呼び出しが個別にテストされていることを前提としていることに注意してください。

テストされていないため、ここにマイナーな構文/エラーがある可能性があります。しかし、プロセスメソッドをテストする方法についてのアイデアが得られます

describe "Process" do
  it "should do nothing if the event is not accepted" do
    webhook = Webhook.new
    webhook.stub(:event_accepted?).and_return(false)
    InvoiceMailer.should_not_receive(:payment_succeeded_email)
    InvoiceMailer.should_not_receive(:payment_failed_email)
    webhook.process
  end

  it "should send a payment succeeded email if the event type is success" do
    customer = FactoryGirl.create(:user)
    webhook = Webhook.new({"type": "invoice.payment_succeeded", "data": {"object": {"id": 1, "customer": customer.id}}})
    Stripe::Invoic.should_receive(:retrieve).with("1").and_return(invoice = double("invoice", :amount_due => 20))
    InvoiceMailer.should_receive(:payment_succeeded_email).with(customer, invoice)
    webhook.process
  end

  it "should do nothing if the event type is success but the invoice due is zero" do
  end

  it "should log when there is an exception in processing the successful payment" do
  end

  it "should expire the user if the subscription is deleted" do
    customer = FactoryGirl.create(:user)
    webhook = Webhook.new({"type": "customer.subscription.deleted", "data": {"object": {"id": 1, "customer": customer.id}}})
    User.stub(:find_by_customer_id).with(customer.id).and_return(customer)
    customer.should_receive(:expire!)
    webhook.process
  end

  it "should do nothing if the subscription is deleted and the user is invalid" do
    webhook = Webhook.new({"type": "customer.subscription.deleted", "data": {"object": {"id": 1, "customer": customer.id}}})
    User.stub(:find_by_customer_id).with(customer.id).and_return(nil)
    User.any_instance.should_not_receive(:expire!)
    webhook.process
  end

  it "should send a failure email if the payment was not successful" do
  end
end
