Question

我正在使用设计中的request_confirmation_test.rb文件

我也包含了帮助程序，但文件在每一行显示错误。看起来缺少文件正常工作所必需的东西。这是我目前得到的错误

ConfirmationInstructionsTest#test_set_up_sender_from_custom_mailer_defaults:
NoMethodError: undefined method `from' for nil:NilClass
    test/integration/request_confirmation_test.rb:46:in `block in <class:ConfirmationInstructionsTest>'

这是我测试文件的代码

require 'test_helper'

class ConfirmationInstructionsTest < ActionMailer::TestCase

    end
  end

  end

  test 'set up sender from custom mailer defaults' do

  test 'set up subject from I18n' do
    store_translations :en, devise: { mailer: { confirmation_instructions: { subject: 'Account Confirmation' } } } do
      assert_equal 'Account Confirmation', mail.subject
    end
  end

      assert_equal 'User Account Confirmation', mail.subject
    end
  end

  test 'body should have user info' do
    assert_match user.email, mail.body.encoded
  end

  test 'body should have link to confirm the account' do
    host, port = ActionMailer::Base.default_url_options.values_at :host, :port

    if mail.body.encoded =~ %r{<a href=\"http://#{host}:#{port}/users/confirmation\?confirmation_token=([^"]+)">}
      assert_equal $1, user.confirmation_token
    else
      flunk "expected confirmation url regex to match"
    end
  end

  # test 'renders a scoped if scoped_views is set to true' do
  #   swap Devise, scoped_views: true do
  #     assert_equal user.email, mail.body.decoded
  #   end
  # end

  # test 'renders a scoped if scoped_views is set in the mailer class' do
  #   begin
  #     Devise::Mailer.scoped_views = true
  #     assert_equal user.email, mail.body.decoded
  #   ensure
  #     Devise::Mailer.send :remove_instance_variable, :@scoped_views
  #   end
  # end

  test 'mailer sender accepts a proc' do
    swap Devise, mailer_sender: proc { "another@example.com" } do
      assert_equal ['another@example.com'], mail.from
    end
  end
end
