Question

目前在我的控制器规范中我有：

require 'spec_helper'

describe CustomerTicketsController do
  login_user

  describe "POST /create (#create)" do
    # include EmailSpec::Helpers
    # include EmailSpec::Matchers
    it "should deliver the sales alert email" do
      # expect
      customer_ticket_attributes = FactoryGirl.attributes_for(:customer_ticket)
      customer_mailer = mock(CustomerMailer)
      customer_mailer.should_receive(:deliver).
        with(CustomerTicket.new(customer_ticket_attributes))
      # when
      post :create, :customer_ticket => customer_ticket_attributes
    end
  end
end

在我的控制器中我有：

  # POST /customer_tickets
  # POST /customer_tickets.xml
  def create
    respond_to do |format|
      if @customer_ticket.save
        CustomerMailer.sales_alert(@customer_ticket).deliver
        format.html { redirect_to @customer_ticket, notice: 'Customer ticket was successfully created.' }
        format.xml { render xml: @customer_ticket, status: :created, location: @customer_ticket }
      else
        format.html { render action: "new" }
        format.xml { render xml: @customer_ticket.errors, status: :unprocessable_entity }
      end
    end
  end

我的测试目前产生以下输出：

  1) CustomerTicketsController POST /create (#create) should deliver the sales alert email

感谢您的关注。

Answer 1

您可以检查ActionMailer :: Base.deliveries.count以确保它增加1。

像这样（未经测试）

expect {custom_mailer.deliver}.to change { ActionMailer::Base.deliveries.count }.by(1)

Answer 2

您正在设置的模拟与实际执行的模拟不匹配。你必须在你正在创建的那个模拟器上调用deliver。

像

这样的东西

message = mock('Message')
CustomerMailer.should_receive(:sales_alert).and_return(message)
message.should_receive(:deliver)

应该通过。

如果你想检查传递给sales_alert的内容你正在做什么将无法工作 - 活动记录只会按主键相等比较对象，所以你在规范中创建的客户票证' t等于控制器中创建的那个。

你可以做的一件事是

CustomerMailer.should_receive(:sales_alert) do |arg|
  ...
end.and_return(message)

rspec会产生调用的sales_alert，你可以做任何你想要的检查

另一种方法是将CustomerTicket.new存根，然后再控制它返回的内容，例如

mock_ticket = mock(CustomerTicket)
CustomerTicket.should_receive(:new).with(customer_ticket_attributes).and_return(mock_ticket)
mock_ticket.should_receive(:save).and_return(true)
CustomerMailer.should_receive(:sales_alert).with(mock_ticket).and_return(message)

最后，您可能会认为此警报发送应该属于CustomerTicket的实例方法，在这种情况下，您的控制器规范只能检查是否在故障单上调用了send_sales_alert方法。

Answer 3

这是如何测试使用正确参数调用Mailer的方法。

delivery = double
expect(delivery).to receive(:deliver_now).with(no_args)

expect(CustomerMailer).to receive(:sales_alert)
  .with(customer_ticket)
  .and_return(delivery)

如何编写确保发送电子邮件的Rspec控制器测试？
