如果发送电子邮件，如何使用 RSpec 进行测试 [英] How to test with RSpec if an email is delivered

问题描述

如果我使用 :post 调用控制器方法，我想测试是否发送了电子邮件.我将使用 email_spec 所以我在这里尝试了这个:http://rubydoc.info/gems/email_spec/1.2.1/file/README.rdoc#Testing_In_Isolation

I'd like to test if an email is delivered if I call a controller method with :post. I'll use email_spec so I tried this snipped here: http://rubydoc.info/gems/email_spec/1.2.1/file/README.rdoc#Testing_In_Isolation

但它不起作用，因为我将模型对象的一个​​实例传递给了交付方法，并且该实例在交付之前已保存.

But it doesn't work, because I pass an instance of the model-object to the delivery-method and the instance is saved before the delivery.

我尝试创建模型对象的另一个实例，但 ID 不相同.

I tried to create an other instance of the model-object, but then the id isn't the same.

我的控制器方法如下所示:

My controller-method looks like this:

def create

   @params = params[:reservation]

   @reservation = Reservation.new(@params)
   if @reservation.save
      ReservationMailer.confirm_email(@reservation).deliver
      redirect_to success_path
   else
      @title = "Reservation"
      render 'new'
   end

end

你有什么办法解决这个问题吗?

Do you have any idea to solve this?

推荐答案

假设您的测试环境以通常的方式设置(即，您有 config.action_mailer.delivery_method = :test)，然后将发送的电子邮件作为 Mail::Message 实例插入到全局数组 ActionMailer::Base.deliveries 中.您可以从测试用例中读取该信息并确保电子邮件符合预期.请参阅此处.

Assuming your test environment is set up in the usual fashion (that is, you have config.action_mailer.delivery_method = :test), then delivered emails are inserted into the global array ActionMailer::Base.deliveries as Mail::Message instances. You can read that from your test case and ensure the email is as expected. See here.
