以下是测试的基本问题:
Update the spec so that whenever a tweet is created, we verify that email_tweeter is called on the tweet object. ***I can not alter the models, question, or mailer.***
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内容:更新
describe Tweet do
context 'after create' do
let(:zombie) { Zombie.create(email: 'anything@example.org') }
let(:tweet) { zombie.tweets.new(message: 'Arrrrgggghhhh') }
it 'calls "email_tweeter" on the tweet' do
tweet.email_tweeter.should_receive(:zombie)
tweet.save
end
end
end
错误信息是:
Failures:
1) Tweet after create calls "email_tweeter" on the tweet
Failure/Error: tweet.email_tweeter.should_receive(:zombie)
NoMethodError:
private method `email_tweeter' called for #<Tweet:0x000000062efb48>
# zombie_spec.rb:7:in `block (3 levels) '
Finished in 0.26328 seconds
1 example, 1 failure
Failed examples:
rspec zombie_spec.rb:6 # Tweet after create calls "email_tweeter" on the tweet
任何rspec偷看都可以指出我在这里错过了什么?谢谢。

这个怎么样:
it 'calls "email_tweeter" on the tweet' do
tweet.should_receive(:email_tweeter)
tweet.save
end

这样做
it 'calls "email_tweeter" on the tweet' do
tweet.email_tweeter.should_receive(:zombie)
tweet.save
end

卸下:
private :email_tweeter
您无法测试私有方法。
更新
事实上,您可以测试私有方法(使用不关心隐私的send
或eval
方法),但您不应该这样做,因为这些是实现的一部分而不是最终输出。在您的测试中,您应该保存一条新推文,检查是否已发送电子邮件。实现细节可以随时间变化,只要邮件正在发送,它就不应该影响测试。例如,您可以尝试:
it 'generates and sends an email' do
tweet.save
ActionMailer::Base.deliveries.last.message.should eq tweet.message
end
