私のRspec+Capybara統合テストは、Capybara-Webkitを使用してJavascriptに依存するインターフェイス要素との対話を開始するまでは正常に機能していました。

Capybara-Webkitを使おうとすると、以下の空白ページが表示されsave_and_open_lineます。なんで?

/spec/features/area_spec.rb

require 'spec_helper'
describe "Area" do
  ...
  describe "Admin" do
    ...  
    before(:each) do
      Capybara.current_driver = :webkit
      @virginia = User.create(
        :username => "Virginia", 
        :password => "password", 
        :password_confirmation => "password", 
        :email => "example@example.com")
      @admin = Role.create(:name => "admin")    
      @assignment = Assignment.create(user_id: @virginia.id, role_id: @admin.id)
      visit login_path
      fill_in 'user_session_username', :with => @virginia.username
      fill_in 'user_session_password', :with => @virginia.password
      click_on 'submit_user_session'
      visit report_path(@report)
      save_and_open_page
      page.find('#nav_reports').trigger(:mouseover)
      ...
    end
    ...
  end
  ...
end

/spec/spec_helper.rb

require 'rubygems'
require 'spork'
require 'database_cleaner'
Spork.prefork do
end
Spork.each_run do
end
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'capybara/rspec'
require 'capybara/rails' 
require 'capybara/dsl' 
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
RSpec.configure do |config|
  config.mock_with :rspec
  config.fail_fast = true
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.before(:each) { ActionMailer::Base.deliveries.clear }
  config.use_instantiated_fixtures = false 
  config.include(Capybara, :type => :integration)
  Capybara.javascript_driver = :webkit
  config.use_transactional_fixtures = false
  config.before(:suite) do
    DatabaseCleaner.clean_with :truncation
  end
  config.before(:each) do
    if example.metadata[:js]
      DatabaseCleaner.strategy = :truncation
    else
      DatabaseCleaner.strategy = :transaction
    end
    DatabaseCleaner.start
  end
  config.after(:each) do
    DatabaseCleaner.clean
  end
end

Capybara.current_driver = :webkitから削除するとarea_spec.rb(ただし、Webkit関連のコードはそのままにしておきますspec_helper.rb)、によって生成されたページsave_and_open_pageは空ではありませんが、Rspecコマンドラインで次のエラーが発生します。

Failure/Error: page.find('#nav_reports').trigger(:mouseover)
     Capybara::NotSupportedByDriverError:
       Capybara::NotSupportedByDriverError

最初:js => :trueはbeforeに追加しようとしましたblock ... doが、Rspecは構文を拒否し続けました。ブロックでカバーされる:js => true最初のページに追加すると、で空白のページが表示されますが、Rspecコマンドラインでのエラーは次のように変わります。it ... do blockbefore ... dosave_and_open_page

Failure/Error: page.find('#nav_reports').trigger(:mouseover)
     Capybara::Webkit::NodeNotAttachedError:
       Capybara::Webkit::NodeNotAttachedError

ファイルCapybara.javascript_driver = :webkit内のレベルをブロック外に移動すると、同じエラーが発生します。spec_helper.rbRspec.configure do

ブロックからすべての行を切り取り、それをカバーする予定before ... doの最初の行に貼り付けると、同じエラーが発生します。it ... do block

Webkit関連のすべてのコードを設定および削除すると、Javascriptドライバーが必要なのconfig.use_transactional_fixtures = true場合を除いて、仕様は機能します。page.find('#nav_reports').trigger(:mouseover)

更新page.current_path.should == report_path(@report):の前に挿入しsave_and_open_page、Capybara-Webkitに関する何かが私visit report_path(@report)の動作を妨げていることを発見しました。(Capybara-WebkitでJavascriptに依存するインターフェイス要素をテストしない場合は正常に機能します。)エラーコードは次のとおりです。

 Failure/Error: page.current_path.should == report_path(@report)
       expected: "/reports/3"
            got: nil (using ==) 

さらなる更新:Capybara-Webkitを使用すると、訪問する直前にステートメントを行のすぐ上@reportに移動しても、Rspecがオブジェクトを見つけるのに問題があることがわかりました。完全なテストログは以下のとおりです。@report = Report.create(...)report_path(@report)

capybara-webkit 1.3.1、capybara 2.1.0 を使用しています

これは、304 ステータス コードが返されたために発生していました。何らかの理由で Capybara Webkit がページをレンダリングせず (おそらく 2xx 以外のコードが原因)、空白のページを返すと思います。

ヘッダーをキャッシュ不可に設定すると、この問題は解決しました。

私は同様の問題を抱えていますが、正確な問題を見つけようとしていますが、page.visit代わりに使用するvisitと役立つようです。
