为什么我不建议"在全球范围内包括Capybara :: DSL!"

Question

每次运行规范时,即使规范通过,例如

$ rspec spec/integration/view_homepage_spec.rb 
including Capybara::DSL in the global scope is not recommended!
.

我的Gemfile有:

group :test, :development do
  gem 'rspec-rails'
  gem 'capybara'
end

我的spec_helper有:

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara'
include Capybara::DSL
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f } 
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
RSpec.configure do |config|
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"
end

如果我注释掉include Capybara::DSL那么我的水豚方法就像visit不工作一样.

因为Capybara::DSL不建议包括在全球范围内.

这包括系统中全局的许多方法,这些方法可能会干扰您自己的代码.

这是正确的方法:

RSpec.configure do |config|
  config.include Capybara::DSL, :type => :feature
end
