ruby-on-rails - Rspec 找不到 ActiveAdmin Controller

Question

我正在尝试使用 rspec 在 ActiveAdmin 中测试自定义成员操作。

app/admin/inactive_user.rb

ActiveAdmin.register InactiveUser do
  member_action :activate, method: :put do
    user = User.new(email: resource.email, password: generate_activation_code)
    resource.destroy if user.save
    send_activation_email user
    redirect_to admin_inactive_users_path, notice: "#{user.email} was activated"
  end
end

app/spec/admin/inactive_user_controller_spec.rb

require 'spec_helper'

describe Admin::InactiveUserController do
  render_views

  before do
    @admin = FactoryGirl.create(:admin, confirmed_at: Date.yesterday)
    authenticate_user @admin
  end

  describe "PUT #activate" do
    before(:each) do
      @inactive_user = FactoryGirl.create(:inactive_user)
      put :activate, id: @inactive_user.id
    end

    it "should redirect to inactive users index" do
      expect(response).to redirect_to(admin_inactive_users_path)
    end
  end
end

我收到这个错误:

NameError:
  uninitialized constant Admin
# ./spec/admin/inactive_user_controller_spec.rb:3:in `<top (required)>'

我试过了this没有任何运气。

另外，如果您知道有任何项目使用 rspec 对这类事情进行测试，那就太好了，文档没有说太多。

更新:现在它在测试后运行 active_admin 初始值设定项:加载时出错

NameError:
  uninitialized constant Admin
# ./spec/admin/inactive_user_controller_spec.rb:3:in `<top (required)>'

[3, 12] in /Users/lucia/Documents/frogs-api-remote/config/initializers/active_admin.rb
    3:   # == Site Title
    4:   #
    5:   # Set the title that is displayed on the main layout
    6:   # for each of the active admin pages.
    7:   #
=>  8:   config.site_title = "Frogs App"
    9:
   10:   # Set the link url for the title. For example, to take
   11:   # users to your main site. Defaults to no link.
   12:   #

尝试使用 rails_helper 而不是 spec_helper，参见 How is spec/rails_helper.rb different from spec/spec_helper.rb? Do I need it?

rails_helper 应该需要 File.expand_path("../../config/environment", __FILE__) 然后 config/environment 应该调用 Rails.application.initialize! 并且应该在测试开始之前加载 initalizers/active_admin.rb 并定义 Admin::InactiveUserController。

initializers/active_admin 运行后，您应该能够检查 ActiveAdmin.application.namespaces.map(&:name)，在您的情况下应该是 [:admin]。如果是，则检查 ActiveAdmin.application.namespaces[:admin].resources.map(&:c‌ ontroller)，它应该会为您提供已创建的 Controller 列表。
