ruby-on-rails - ActionMailer::Base.deliveries 在 Rspec 中始终为空

Question

我正在尝试使用 rspec 测试一些邮件程序，但交付始终为空。这是我的 rspec 测试:

require "spec_helper"

describe "AccountMailer", :type => :helper do
  before(:each) do
    ActionMailer::Base.delivery_method = :test
    ActionMailer::Base.perform_deliveries = true
    ActionMailer::Base.deliveries = []
  end

  it "should send welcome email to account email" do
    account = FactoryGirl.create :account
    account.send_welcome_email

    ActionMailer::Base.deliveries.empty?.should be_false
    ActionMailer::Base.deliveries.last.to.should == account.email
  end
end

它失败了:

1) AccountMailer should send welcome email to account email
     Failure/Error: ActionMailer::Base.deliveries.empty?.should be_false
        expected true to be false

我的 send_welcome_email 函数如下所示(这是我的模型):

def send_welcome_email 
    AccountMailer.welcome self
end

还有我的邮件:

class AccountMailer < ActionMailer::Base
  default from: APP_CONFIG['email']['from']

  def welcome data
    if data.locale == 'es'
      template = 'welcome-es'
    else
      template = 'welcome-en'
    end

    mail(:to => data.email, :subject => I18n.t('welcome_email_subject'), :template_name => template)
  end
end

有任何想法吗？我不确定如何继续。

您是否在实际运行应用程序时测试过它是否有效？也许您的测试失败是正确的。

我注意到你从不给 deliver 打电话当您创建邮件时，所以我怀疑测试失败了，因为实际上没有发送电子邮件。我期待您的 send_welcome_email看起来更像的方法

def send_welcome_email 
  AccountMailer.welcome(self).deliver
end
