與工廠女孩建設的麻煩

所以問題是郵件沒有被添加到ActionMailer :: Base.deliveries。與工廠女孩建設的麻煩

FactoryGirl.create返回零。我究竟做錯了什麼？

FactoryGirl.define do 
    factory :provisional_user do 
    sequence(:email) { |n| "bangbang_#{n}@example.com" } 
    first_name "Provisional" 
    last_name "User" 
    partner "source2" 
    unsubscribed false 
    end 

    factory(:unsubscribed_user, :parent => :provisional_user, :class => ProvisionalUser) do 
    sequence(:email) { |n| "[email protected]" } 
    first_name "Unsubscribed" 
    last_name "User" 
    partner "source2" 
    unsubscribed true 
    end 


    factory(:subscribed_user, :class => ProvisionalUser) do 
    sequence(:email) { |n| "[email protected]" } 
    first_name "Subscribed" 
    last_name "User" 
    partner "source2" 
    unsubscribed false 
    end 
    ... 
end

然後在我的測試（我也嘗試FactoryGirl.create沒有節省以下行！）：

require "rspec" 
require "spec_helper" 
require "action_mailer" 

describe "unsubscribe functionality" do 

    before(:each) do 
    ActionMailer::Base.deliveries = [] 
    end 

    it "should send emails to subscribed users only" do 
    unsubscribed_user = FactoryGirl.build(:unsubscribed_user) 
    unsubscribed_user.save! 

    subscribed_user = FactoryGirl.create(:subscribed_user) 
    puts "the user is" + subscribed_user.to_s 
    CoRegEmailWorker.perform 
    #sent.length.should == 1 
    sent.first.email.should =~ subscribed_user.email 
    sent.first.email.should_not =~ unsubscribed_user.email 
    end 

    def sent 
    ActionMailer::Base.deliveries 
    end 

end

，但它的失敗是這樣的：

Failure/Error: sent.first.email.should =~ subscribed_user.email 
    NoMethodError: 
    undefined method `email' for nil:NilClass 
    # ./spec/mailers/provisional_users_notifier_spec.rb:21
