ruby-on-rails - 为邮件 rails 编写测试

Question

我正在尝试测试一个邮件发送方法，它应该只向经过验证的用户发送邮件。

所以我的邮件程序中有这样一个方法:

def send_hints(user)
    @user = user
    mail :to => user.email, :subject => "Your hints for the day"
end

我正在努力确保只有经过验证的用户才能收到此信息。所以 user.verified_at 不是 null/nil。

现在开始写测试:

describe "Emails should be sent only to verified user"
  let(:user) { FactoryGirl.create(:user, :verified_at => DateTime.now) }
  let(:mail) { UserMailer.send_hints(user) }
...

我不确定在这里断言什么是明智的？如果我以相反的方式发送邮件，则应该发送或不应该发送邮件。

这是一种测试方法:

# config/environments/test.rb
YourApplication::Application.configure do
  config.action_mailer.delivery_method = :test
end


# spec/your_spec.rb
describe 'Emails should be sent only to verified user' do
  let(:user) { FactoryGirl.create(:user, verified_at: verified_at) }
  before { UserMailer.send_hints(user) }
  subject { ActionMailer::Base.deliveries.last.to }
  context 'When the user is verified' do
    let(:verified_at) { DateTime.now }
    it { should include(user.email) }
    end
  end

  context 'When the user is not verified' do
    let(:verified_at) { nil }
    it { should_not include(user.email) }
  end
end
