Question

以下是测试的基本问题：

We've changed the code below so we're mocking ZombieMailer.tweet method instead of the entire method. There is still more to do to make this example work. First, finish the let(:mail) statement below by creating a stub with a deliver method that returns true.
Then update the mock so the call to the tweet method returns the mail stub you created.

不幸的是我无法改变模型，问题或邮件。

型号：

# tweet.rb
class Tweet < ActiveRecord::Base
  belongs_to :zombie
  validates :message, presence: true
  attr_accessible :message

  after_create :email_tweeter

  def email_tweeter
    ZombieMailer.tweet(zombie, self).deliver
  end
  private :email_tweeter
end

# zombie.rb
class Zombie < ActiveRecord::Base
  has_many :tweets
  validates :email, presence: true
  attr_accessible :email
end

邮件程序：

class ZombieMailer < ActionMailer::Base
  def tweet(zombie, tweet)
    mail(:from => 'admin@codeschool.com',
         :to => zombie.email,
         :subject => tweet.message)
  end
end

我一直在这方面蹦蹦跳跳，可以使用一些指针。以下是我现在一直在使用的测试问题3.现在他们要求添加传递方法，但他的方法不存在，或者至少我没有把它放在正确的位置。

已更新

describe Tweet do
  context 'after create' do
    let(:zombie) { Zombie.create(email: 'anything@example.org') }
    let(:tweet) { zombie.tweets.new(message: 'Arrrrgggghhhh') }
    let(:mail) { stub(:deliver => true) }

    it 'calls "tweet" on the ZombieMailer' do
      ZombieMailer.should_receive(:tweet).returns(:mail)
      tweet.save
    end
  end
end

错误信息是：

Failures:

1) Tweet after create calls "tweet" on the ZombieMailer
Failure/Error: ZombieMailer.should_receive(:tweet).returns(:mail)
NoMethodError:
undefined method `returns' for #<RSpec::Mocks::MessageExpectation:0x0000000519ab90>
# zombie_spec.rb:8:in `block (3 levels) '

1 example, 1 failure

Failed examples:

rspec zombie_spec.rb:7 # Tweet after create calls "tweet" on the ZombieMailer

任何rspec偷看都可以指出我在这里错过了什么？谢谢。

感谢上述评论中的@Paritosh和@Alex，以下是最终答案。

describe Tweet do
  context 'after create' do
    let(:zombie) { Zombie.create(email: 'anything@example.org') }
    let(:tweet) { zombie.tweets.new(message: 'Arrrrgggghhhh') }
     let(:mail) { stub(:deliver => true) }

    it 'calls "tweet" on the ZombieMailer' do
      ZombieMailer.should_receive(:tweet).and_return(mail)
      tweet.save
    end
  end
end
