目前在我的控制器规格中，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

我的测试当前产生以下输出：

Failures:

  1) CustomerTicketsController POST /create (#create) should deliver the sales alert email
     Failure/Error: customer_mailer.should_receive(:deliver).
       (Mock CustomerMailer).deliver(#<CustomerTicket id: nil, first_name: "firstname1", last_name: "lastname1", company: nil, referral: nil, email: "firstname1@example.com", phone: "555-5555", fax: nil, country: nil, address1: "555 Rodeo Dr.", address2: nil, city: "Beverly Hills", state: "CA", postcode: "90210", question: "The answer to the universe is 4.", type: nil, status: nil, priority: nil, number: nil, cs_rep_id: nil, created_at: nil, updated_at: nil>)

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

像这样的东西（未经测试）

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

您设置的模拟与实际执行的不匹配。您实际上必须调用deliver您正在创建的模拟。

就像是

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

应该通过。

如果您想检查传递给sales_alert您正在做的事情的内容是行不通的 - 活动记录只会按主键相等性比较对象，因此您在规范中创建的客户票证将不等于在规范中创建的票证你的控制器。

你可以做的一件事是

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

rspec 将产生任何sales_alert被调用的东西，你可以做任何你想做的检查

另一种方法是 stub out CustomerTicket.new，这样您就可以控制它返回的内容，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，您可能会决定此警报发送应该真正属于实例方法，CustomerTicket在这种情况下，您的控制器规范可以检查是否send_sales_alert在票证上调用了方法。

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)
