我正在阅读 Rails 3 Guides，并查看测试邮件部分。

但是，按照这些说明，我想知道它们是否有问题，并且做出的断言永远不会是真的。

这是文档中的相关部分：

http://guides.rubyonrails.org/testing.html#testing-your-mailers

10.2.2 基本测试用例

在这个测试中，@expected 是 TMail::Mail 的一个实例，您可以在测试中使用它。它在 ActionMailer::TestCase 中定义。上面的测试使用@expected 来构造一个电子邮件，然后它使用自定义邮件程序创建的电子邮件来断言。邀请固定装置是电子邮件的正文，用作要断言的示例内容。帮助程序 read_fixture 用于从该文件中读取内容。

这就是为什么我认为是这样的：

test_card_update_notification(CardSenderMailerTest) [/Users/victorstan/Sites/ContactMonkey/test/unit/card_sender_mailer_test.rb:21]：

注意到区别了吗？

Message-ID: <4f5eb6ee903b3_710a3fd4d6034ec8484b1@Victor-Stans-MacBook-Pro.local.mail>

VS

Message-ID: <4f5eb6eeaeae1_710a3fd4d6034ec848559@Victor-Stans-MacBook-Pro.local.mail>

我该怎么解释呢？据我所知，这不是我的数据或我的控制的一部分。

我正在使用的断言：

assert_equal @expected.encoded, CardSenderMailer.card_update_notification(card, followers, field_updates).encoded

这与文档中使用的非常相似：

assert_equal @expected.encoded, UserMailer.create_invite('me@example.com', 'friend@example.com', @expected.date).encoded

它不漂亮，但我做了如下的事情：

test "able to mail something" do
    # bunch of @expected statements
    assert_equal encode(@expected), encode(MyMailer.mail(@user))
end  

def encode message
    message.encoded.gsub(/Message-ID: <.+>/, '').gsub(/Date: .+/, '')
end

如果您想跨邮件测试共享，请修改test_helper.rb并添加：

class ActionMailer::TestCase
    def encode message
        message.encoded.gsub(/Message-ID: <.+>/, '').gsub(/Date: .+/, '')
    end
end

使用mocha存根“has_message_id？” 有相似的结果。在我的测试中，我添加：

Mail::Message.any_instance.stubs('has_message_id?').returns(true)

我使测试通过.gsub(/Message-ID: <[\s\S]+>/, '')

这样就可以断言：

assert_equal @expected.encoded.gsub(/Message-ID: <[\s\S]+>/, ''), CardSender.card_update_notification(card, followers, field_updates).encoded.gsub(/Message-ID: <[\s\S]+>/, '')
