脱离rails环境单独使用capybara以及使用capybara测试拖放

require 'rubygems'
require 'capybara'
require 'capybara/dsl'

Capybara.run_server = false
Capybara.current_driver = :selenium
Capybara.app_host = 'http://www.google.com'

module MyCapybaraTest
  class Test
    include Capybara
    def test_google
      visit('/')
    end
  end
end

t = MyCapybaraTest::Test.new
t.test_google

注意只有内置的selenium，或者使用其他扩展才能测试javascript，例如drag and drop

describe Capybara::Driver::Selenium do
  before do
    @driver = Capybara::Driver::Selenium.new(TestApp)
  end
 
  it_should_behave_like "driver"
  it_should_behave_like "driver with javascript support"
end

shared_examples_for "driver with javascript support" do
  before { @driver.visit('/with_js') }
 
  describe '#find' do
    it "should find dynamically changed nodes" do
      @driver.find('//p').first.text.should == 'I changed it'
    end
  end
 
  describe '#drag_to' do
    it "should drag and drop an object" do
      draggable = @driver.find('//div[@id="drag"]').first
      droppable = @driver.find('//div[@id="drop"]').first
      draggable.drag_to(droppable)
      @driver.find('//div[contains(., "Dropped!")]').should_not be_nil
    end
  end
 
  describe "#evaluate_script" do
    it "should return the value of the executed script" do
      @driver.evaluate_script('1+1').should == 2
    end
  end
end
