Rails 电子邮件测试失败

Question

我有以下邮件程序：

class RewardMailer < ActionMailer::Base
  default from: 'dude@example.com'

  def invoice_due(invoice_info)
    @btc_address = invoice_info.btc_address
    @alice = invoice_info.alice
    @subject = invoice_info.subject
    mail to: @alice, subject: @subject
  end
end

和运行以下测试：

class RewardMailerTest < ActionMailer::TestCase
  test 'invoice_due' do
    btc_address = '1BITCOINkkkkkkkkkkkk'
    mailman = 'dude@example.com'
    ali = 'ali@example.com'
    subj = 'I Vooshed my website'
    mail = RewardMailer.invoice_due(
      alice: ali,
      subject: subj,
      btc_address: btc_address
    )
    assert_equal subj, mail.subject
    assert_equal [ali], mail.to
    assert_equal [mailman], mail.from
  end
end

给我以下烦人的错误：

ERROR["test_invoice_due", RewardMailerTest, 2015-12-20 16:27:13 +0500]
 test_invoice_due#RewardMailerTest (1450610833.82s)
NoMethodError:         NoMethodError: undefined method `btc_address' for #<Hash:0x00000005307348>
            app/mailers/reward_mailer.rb:6:in `invoice_due'
            test/mailers/reward_mailer_test.rb:10:in `block in <class:RewardMailerTest>'
        app/mailers/reward_mailer.rb:6:in `invoice_due'
        test/mailers/reward_mailer_test.rb:10:in `block in <class:RewardMailerTest>'

我是个白痴，但有人能解释一下为什么这行不通吗？

Answer 1

您在测试中将哈希传递给 RewardMailer.invoice_due 方法，但在该方法的实现中您调用了 btc_address 方法，就像哈希是一个 InvoiceInfo 对象一样。

任一：

在您的测试中创建一个 InvoiceInfo 对象并将其传递给 invoice_due
- i = InvoiceInfo.new(btc_address: "address_here")
- RewardMailer.invoice_due(i)
或修改您的方法以访问散列中的 btc_address 键
- invoice_info[:btc_address]
