我正在使用奇妙的wisper gem对模型的变化做出反应（Rails 4.1）。

Class Transaction < ActiveRecord::Base
  #include Wisper::Publisher
  after_save { broadcast(:transaction_saved)}

end

这broadcast是Wisper::Publisher模块提供的一个方法，如您在上面看到的，它的包含被注释掉了。

由于这一切，我不明白如何通过这样的测试而不抱怨“broadcast缺少方法”：

require 'test_helper'
class TransactionTest < ActiveSupport::TestCase
  include GeneralHelper # this doesnt include any other module
  def setup
    @tr = Transaction.create(...)
  end
  def test_transaction_method
    @tr.update_attributes(amount:100)
  end
end

正如预期的那样，development/production环境确实抱怨缺少方法

- 更新 test/test_helper.rb

ENV["RAILS_ENV"] ||= "test"
require File.expand_path('../../config/environment', __FILE__)
require 'rails/test_help'
require "mocha/mini_test"
require 'minitest/reporters'
Minitest::Reporters.use!(
  Minitest::Reporters::ProgressReporter.new,
  ENV,
  Minitest.backtrace_filter)

# Capybara and poltergeist integration
require "capybara/rails"
require "capybara/poltergeist"
Capybara.javascript_driver = :poltergeist


class ActiveSupport::TestCase
  ActiveRecord::Migration.check_pending!
  include FactoryGirl::Syntax::Methods

  # Setup all fixtures in test/fixtures/*.yml for all tests in alphabetical order.
  #
  # Note: You'll currently still have to declare fixtures explicitly in integration tests
  # -- they do not yet inherit this setting
  fixtures :all

  # Add more helper methods to be used by all tests here...
  def assert_valid(model, msg = nil)
    msg = message(msg) { "Expected #{model} to be valid, but got errors: #{errors}." }
    valid = model.valid?
    errors = model.errors.full_messages.join(', ')
    assert valid, msg
  end
end

你当然可以这样做：

module MyWisper
  def broadcast
    puts 'hello'
  end
end

class SomeClass
  include MyWisper
end

SomeClass.new.broadcast

--output:--
hello

但你也可以这样做：

module MyWisper
  def broadcast
    puts 'hello'
  end
end

def broadcast
  puts 'hi'
end

class SomeClass
  #include MyWisper
  broadcast
end


--output:--
hi

因此，在所有要求的某个地方，您需要一个全局广播（）方法进入您的测试环境。
