ruby-on-rails-3 - Capybara Acceptance DSL 与 MiniTest::Spec？

Question

Capybara 的自述文件(参见 Using Capybara with MiniTest::Spec )说，如果我正确包含该模块，我可以做到这一点，但它没有给出任何说明性示例...我尝试过包含这样的模块:

class MiniTest::Spec
  include Capybara::DSL
end

...没有用。我不断收到此错误:

<main>': undefined methodfeature' for main:Object (NoMethodError)

如何让它按照注释掉的代码中编写的那样工作？

spec/acceptance/api/reward_terms_spec.rb:

require "#{Dir.pwd}/spec/acceptance/acceptance_helper"

# this syntax works...

describe 'reward terms acceptance test' do
  include Capybara::DSL

  describe '#index' do
    specify {
      visit '/reward_terms'
      # ...
    }
  end
end

# this syntax doesn't work...

# feature 'RewardTerms', %q{
#   In order to get all reward terms available to me
#   As an API client
#   I want to list all active RewardTerms
# } do

#   background do
#     set_api_headers
#   end

#   scenario 'RewardTerm index' do
#     visit '/reward_terms'
#     ...
#   end
# end

spec/acceptance/acceptance_helper.rb:

ENV["RAILS_ENV"] = "test"
require "#{Dir.pwd}/config/environment"

require 'minitest/autorun'
require 'capybara/rails'

def set_api_headers(device_id = 'abcd1234')
  header 'Accept', 'application/json'
  header 'X-Device-Id', device_id
end

Answer 1

this post中有一个很好的描述了解如何使 MinitTest::Spec 与 capybara 一起运行。在那里，他基本上将 Capybara::DSL 包含到所有规范的基类中，如下所示

class RequestSpec < MiniTest::Spec
  include Rails.application.routes.url_helpers
  include Capybara::DSL
end

这在我们的设置中工作得相当好，但当然它不会重新打开 MiniTest::Spec。
