capybara rspec更深入的日志？

Question

我正在执行click_button之后的某个点检索单例不能转储错误。所有rspec输出告诉我是：

1) home not logged in sign in should contain content with 'Add new charity 
Failure/Error: click_button "Install" 
TypeError: 
    singleton can't be dumped 
# (eval):2:in `click_button' 
# ./spec/integration/home_spec.rb:29:in `block (4 levels) in <top (required)>' 

我试过使用-b选项，但我没有得到任何新的信息。在我的控制器中使用日志记录功能后，我可以看到该操作完成并通过重定向完成。在此之后的某个时刻，在接收操作被调用之前，它必须失败。所以如果有办法我可以更好地看到堆栈跟踪，我可能能够查明问题。

新增home_spec.rb

使用shopify_api宝石，你可以看到。

require 'spec_helper' 

describe "home" do 

    before do 
    @domain = "myshop.myshopify.com" 
    @token = SecureRandom.hex(16) 
    @shopify_session = ShopifyAPI::Session.new(@domain, @token) 
    end 

    context "not logged in" do 
    it "should be at login" do 
     visit "/" 
     page.should have_content("Install this app in a shop to get access to its private admin data") 
    end 

    describe "sign in" do 
     before do 
     ShopifyAPI::Session.should_receive(:new).and_return(@shopify_session) 

     @shopify_session.should_receive(:valid?).and_return(true) 

     ShopifyAPI::Session.any_instance.should_receive(:create_permission_url).and_return("/login/finalize?shop=#{@domain}&t=#{@token}") 
     end 

     it "should contain content with 'Add new charity" do 
     visit "/" 
     fill_in "shop", with: @domain 
     click_button "Install" 
     page.should have_content("Add new charity") 
     end 
    end 
    end 

    context "logged in" do 
    before do 
     page.set_rack_session(:shopify => @shopify_session) 
    end 

    it "should contain content with 'Add new charity" do 
     visit "/" 
     page.should have_content("Add new charity") 
    end 
    end 

end 

spec_helper.rb：

# This file is copied to spec/ when you run 'rails generate rspec:install' 
ENV["RAILS_ENV"] ||= 'test' 
require File.expand_path("../../config/environment", __FILE__) 
require 'rspec/rails' 
require 'rspec/autorun' 
require 'capybara/rails' 
require 'capybara/dsl' 
require "rack_session_access/capybara" 

# Requires supporting ruby files with custom matchers and macros, etc, 
# in spec/support/ and its subdirectories. 
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f} 

Rails.application.config do 
    config.middleware.use RackSessionAccess::Middleware 
end 

RSpec.configure do |config| 
    # == Mock Framework 
    # 
    # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line: 
    # 
    # config.mock_with :mocha 
    # config.mock_with :flexmock 
    # config.mock_with :rr 
    config.mock_with :rspec 

    # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures 
    config.fixture_path = "#{::Rails.root}/spec/factories" 

    # If you're not using ActiveRecord, or you'd prefer not to run each of your 
    # examples within a transaction, remove the following line or assign false 
    # instead of true. 
    config.use_transactional_fixtures = true 

    # If true, the base class of anonymous controllers will be inferred 
    # automatically. This will be the default behavior in future versions of 
    # rspec-rails. 
    config.infer_base_class_for_anonymous_controllers = false 

    # RSpec automatically cleans stuff out of backtraces; 
    # sometimes this is annoying when trying to debug something e.g. a gem 
    config.backtrace_clean_patterns = [ 
    /\/lib\d*\/ruby\//, 
    /bin\//, 
    /gems/, 
    /spec\/spec_helper\.rb/, 
    /lib\/rspec\/(core|expectations|matchers|mocks)/ 
    ] 
end

你有没有考虑使用类似撬使它更容易些？它与您的home_spec中包含的其中一个文件有关。

在这里您可以找到撬起：https://github.com/pry/pry

然后在你的代码，你可以插入binding.pry，你应该能够拖放到执行环境并检查发生了什么事在IRB般的会议。

否则，您需要发布您的home_spec.rb，以便我们可以开始理论。
