在selenium测试中使用ActiveRecord

阅读更多

ActiveRecord是rails的框架，我们在selenium测试中肯定需要初始化数据或者清理数据库数据以保证各个测试之间的独立性，可以这样用ActiveRecord来初始化或清理数据库

ruby 代码

require 'test/unit'
require 'selenium'
require 'active_record'
ActiveRecord::Base.establish_connection(
  :adapter => "mysql",
  :host => "localhost",
  :username => "dcrm",
  :password => "dcrm",
  :database => "dcrm2_test"
)

class FunctionalTestCase < Test::Unit::TestCase

  @wait_default_time="30000"

  def setup
    initBrowser unless @selenium
  end

  def teardown
    logout
    clear_database
    closeBrowser
  end

  def logout
    @selenium.open "http://localhost:3000/logout"
    wait_default
  end

  def closeBrowser()
    @selenium.stop
  end

  def initBrowser
    @selenium = Selenium::SeleniumDriver.new("localhost", 4444, "*iexplore", "http://localhost:4444", 10000);
    @selenium.start
  end

  def wait_default
    @selenium.wait_for_page_to_load @wait_default_time
  end

  def test_logout
    logout
    @selenium.is_text_present("用户登录")
  end

  def clear_database
    connection = ActiveRecord::Base.connection
    connection.execute("DELETE from channels")
    ......
  end

end

其中

ruby 代码

require 'active_record'
ActiveRecord::Base.establish_connection(
  :adapter => "mysql",
  :host => "localhost",
  :username => "dcrm",
  :password => "dcrm",
  :database => "dcrm2_development"
)

建立了DB Connection
