我正在构建一个使用React组件进行布局的Rails应用程序，在这里你可以看到一个例子
rails_helper.rb我正在试图用菠菜测试这个，但看起来组件没有在测试中呈现，我想知道是否有办法用菠菜测试React组件，如果有，我是什么丢失？
这是我的# This file is copied to spec/ when you run 'rails generate rspec:install'
require 'spec_helper'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'capybara/poltergeist'
Capybara.javascript_driver = :poltergeist
# Add additional requires below this line. Rails is not loaded until this point!
require 'rspec/rails'
require 'support/factory_girl'
# Requires supporting ruby files with custom matchers and macros, etc, in
# spec/support/ and its subdirectories. Files matching `spec/**/*_spec.rb` are
# run as spec files by default. This means that files in spec/support that end
# in _spec.rb will both be required and run as specs, causing the specs to be
# run twice. It is recommended that you do not name files matching this glob to
# end with _spec.rb. You can configure this pattern with the --pattern
# option on the command line or in ~/.rspec, .rspec or `.rspec-local`.
#
# The following line is provided for convenience purposes. It has the downside
# of increasing the boot-up time by auto-requiring all files in the support
# directory. Alternatively, in the individual `*_spec.rb` files, manually
# require only the support files necessary.
#
# Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }
# Checks for pending migration and applies them before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.maintain_test_schema!
RSpec.configure do |config|
config.include RSpecFeaturesHelper, type: :feature
config.include Devise::TestHelpers, type: :controller
config.include ControllerHelpers, type: :controller
# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
config.fixture_path = "#{::Rails.root}/spec/fixtures"
# 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 = false
# RSpec Rails can automatically mix in different behaviours to your tests
# based on their file location, for example enabling you to call `get` and
# `post` in specs under `spec/controllers`.
#
# You can disable this behaviour by removing the line below, and instead
# explicitly tag your specs with their type, e.g.:
#
# RSpec.describe UsersController, :type => :controller do
# # ...
# end
#
# The different available types are documented in the features, such as in
# https://relishapp.com/rspec/rspec-rails/docs
config.infer_spec_type_from_file_location!
# Filter lines from Rails gems in backtraces.
config.filter_rails_from_backtrace!
# arbitrary gems may also be filtered via:
# config.filter_gems_from_backtrace("gem name")
<ReactOnRails::TestHelper class="configure_rspec_to_compile_assets">
<config></config>
</ReactOnRails::TestHelper>

Capybara支持RSpec和Cucumber根据每个测试中指定的元数据切换到Capybara.javascript_driver中指定的驱动程序。但它对菠菜内置没有任何支持。如果您希望能够指定每个测试使用哪个驱动程序，则需要在此处实现钩子之前实现两个Cucumber的等效 - https://github.com/teamcapybara/capybara/blob/master/lib/capybara/cucumber.rb#L17 - 对于Spinach，然后指定特定测试需要JS。如果您只是希望所有Capybara驱动的测试都使用支持JS的驱动程序，则应指定default_driver而不是javascript_driver
Capybara.default_driver = :poltergeist
注意：当前版本的PhantomJS - 2.1.1（由Poltergeist使用）仅支持ES5 max，因此要使其与React配合良好，您需要确保所有JS都被转换为ES5兼容。它支持的CSS也有限，基本上相当于一个7岁的浏览器。今天更好的（在JS / CSS支持方面）解决方案是使用带有硒的Chrome无头测试，如果使用最新的Capybara，可以使用
指定Capybara.default_driver = :selenium_chrome_headless
