【问题描述】：

我已经安装了一个 gem rspec-rails。除ActiveJob 外，一切正常。我试图在 RSpec 中实现ActiveJob：

include ActiveJob::TestHelper

这是 RSsec 作业控制器的代码：

describe "#perform_later" do
  it "Send Invoice Reminder" do
    ActiveJob::Base.queue_adapter = :test
    InvoiceReminderJob.perform_later
    expect(InvoiceReminderJob).to have_enqueued_job
  end
end

spec_helper.rb:

require 'rails_helper'
RSpec.describe InvoiceReminderJob, type: :job do
  include ActiveJob::TestHelper
  # pending "add some examples to (or delete) #{__FILE__}"

  describe "#perform_later" do
    it "Send Invoice Reminder" do
      ActiveJob::Base.queue_adapter = :test
      InvoiceReminderJob.perform("test")
      expect(InvoiceReminderJob).to have_enqueued_job
    end
  end
end

invoice_reminder_job_spec.rb:

require 'rails_helper'

RSpec.describe InvoiceReminderJob, type: :job do
  # include ActiveJob::TestHelper
  # pending "add some examples to (or delete) #{__FILE__}"

  describe "#perform_later" do
    it "Send Invoice Reminder" do
      ActiveJob::Base.queue_adapter = :test
      InvoiceReminderJob.perform_later
      expect(InvoiceReminderJob).to have_enqueued_job
    end
  end
end

当我尝试使用命令 rspec 运行 rspec 时，出现以下错误：

未初始化的常量 ActiveJob (NameError)

这是我的Gemfile：

这是包含在我的项目中的 gemfile：

group :development, :test do

  gem 'activejob'
  gem 'factory_bot_rails'
end

这是bundle show activejob的输出：

/Users/221/.rvm/gems/ruby-2.1.2/gems/activejob-0

我尝试了很多解决方案，但我无法解决这个问题。如果有人可以帮助我，我将非常感激。

【问题讨论】：

1. activejob 是主应用程序的依赖项，包括生产环境。您不应将 gem 放在 :development 和 :test 组中，而应将其安装在所有环境中（即块外）。
2.我不明白你为什么要在spec_helper.rb 中编写（同样的！）测试。该文件，顾名思义，应该包含 helpers，而不是测试。当然不会重复测试。你甚至在任何地方requireing 那个文件吗？
3.即使这样说，我也不明白为什么你会得到一个 "uninitialized constant ActiveJob" 错误。您能否尝试运行bundle exec rspec，并显示full 错误（如果它仍然存在）？
不是ActiveJob::TestHelper，而是ActiveJobHelpers。

【解决方案1】：

您使用的是rails 4.1.5，在rails 4.2中引入了ActiveJob

使用 gem "gem 'activejob_backport' 解决了这个问题
