ruby-on-rails-3 – Capybara&RSpec

我创建了一个新的rails 3.1项目(rails new test -T).

的Gemfile：

source 'http://rubygems.org'

gem 'rails','3.1.3'

gem 'sqlite3'

group :assets do
  gem 'sass-rails','~> 3.1.5'
  gem 'coffee-rails','~> 3.1.1'
  gem 'uglifier','>= 1.0.3'
end

gem 'jquery-rails'

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

我已经安装了spec文件夹：rails g rspec：install.

投机/ spec_helper.rb：

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment",__FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  config.mock_with :rspec
  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
end

最后我的测试文件：

require 'spec_helper'

feature "the test" do
  scenario "GET /" do
    visit('/')
    page.should have_text('Welcome aboard')
  end
end

所以我启动了rspec：bundle exec rspec spec / my_test.rb,这是错误：

F

Failures:

  1) the test GET /
     Failure/Error: page.should have_text('Welcome aboard')
     NoMethodError:
       undefined method `has_text?' for #<Capybara::Session>
     # ./spec/my_test.rb:6:in `block (2 levels) in <top (required)>'
