所以我用RSpec和email_spec gem测试电子邮件，我不断遇到这个错误，这让我没有真正的线索来了解导致它的原因。
我对RSpec和一般测试都很陌生。当我用Google搜索时发现错误，我发现one post类似于此错误以及错误上的brief documentation page（这对我来说非常模糊）。
我认为原因是email_spec可能过时的宝石或方法，但我只是 spec ulating（你的时间有一个双关语）。
这是我一直收到的错误（我在此帖子上编辑了我的电子邮件）：
1) UserMailer it sends an activation email when the user signs up should be delivered from XXXXXXXX@gmail.com
Failure/Error: it { should deliver_from "XXXXXXXX@gmail.com" }
NoMethodError:
undefined method `addrs' for #<Mail::UnstructuredField:0x007fc5c680bf18>
# ./spec/mailers/user_mailer_spec.rb:12:in `block (3 levels) in <top (required)>'
很少有事情需要指出：
addrs方法（所以我相信）Email::Helpers文件中加入了Email::Matchers和config/test.rb。这是我的UserMailer测试：
require "spec_helper"
require "email_spec"
describe UserMailer do
describe "it sends an activation email when the user signs up" do
user = FactoryGirl.build(:user)
subject { UserMailer.activate_account(user) }
it { should deliver_to user.email }
# Error seems to be occurring from the "deliver_from" method
it { should deliver_from "XXXXXXX2@gmail.com" }
it { should have_subject "Please confirm to activate your account." }
it { should have_body_text "Hi, #{user.first_name}" }
it { should have_body_text "Confirm Your Account" }
end
端
我希望得到帮助，并指出正确的方向是什么导致了这个问题，所以我可以采取适当的步骤来解决它。

出色！我弄清楚了。
问题出现在我的UserMailer课程中（/app/mailers/user_mailer.rb）。
顶部的default from:语句与我的测试不匹配。
class UserMailer < ApplicationMailer
default from: "XXXXXXXX2@gmail.com" # <= This was the culprit
def activate_account(user)
@user = user
mail(:to => @user.email, :subject => "Please confirm to activate your account.")
end
end

我最近碰到了这个问题，我的问题是我在:to字段中没有提供正确的电子邮件地址
我错了 -
mail(to: @user)
而不是
mail(to: @user.email)
