Question

以下是Rails 3.1.12应用中test.rb环境文件中的一行：

config.action_mailer.default_url_options = config.action_controller.default_url_options = { :host => "127.0.0.1", :port => 3000 }

现在这是我做的测试：

subject { get :success }
subject.should redirect_to(:home)

这会产生错误：

Failure/Error: subject.should redirect_to(:home)
       Expected response to be a redirect to <http://127.0.0.1:3000/> but was a redirect to <http://test.host/>

我做错了什么？或者，在哪里配置测试主机？

这是spec_helper.rb文件以供完整参考。

# 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/rspec'

# 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}

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

  # 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 = 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

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
end
Capybara.configure do |config|
  config.app_host    = 'http://127.0.0.1'
  config.server_port = 3000
end

要使用Capybara设置应用主机和服务器端口，请在spec/spec_helper.rb文件中添加以下行

Capybara.configure do |config|
  config.app_host   = 'http://127.0.0.1'
  config.server_port = 3000
end

这对我有用：

# spec/controllers/whatever_controller_spec.rb
before :each do
  @request.host = '127.0.0.1:3000'
end

基于@ dan-reedy提供的链接。在config / environments，spec / spec_helper.rb中再次配置完全相同的参数是非常烦人的，这里......所有方式都略有不同（使用'http：//'或不带，指定端口号或端口分别）。即使Capybara.configure语法似乎也无法在版本之间保持一致......

但是试一试，看看是否能解决它。

以下似乎为我解决了问题的解决方法：

在spec / rails_helper.rb中添加此

module ActionDispatch
  class TestRequest
    # Override host, by default it is test.host
    def host
      'localhost:3000'
    end
  end
end

在Rspec测试Rails重定向的test.host
