Ruby初学者试图从Ruby中的另一个类调用一个方法？

Question

我试图让以下工作.不确定我失败的地方.我收到以下错误:

1)错误:

test_google(Google):
NoMethodError: undefined method `new' for Method:Class
    google.rb:15:in `setup'

我是ruby的新手,所以这很漂亮101.有人可以向我解释我的错误以及为什么我能理解.谢谢!

require "test/unit"
require "selenium-webdriver"
require "json"
require "time"
require_relative "methods"

class Google < Test::Unit::TestCase

  def setup
    @driver = Selenium::WebDriver.for :firefox
    @base_url = "https://www.google.com/"
    @accept_next_alert = true
    @driver.manage.timeouts.implicit_wait = 30
    @verification_errors = []
    @search = Method.new()
  end 

  def teardown
    @driver.quit
    assert_equal [], @verification_errors
  end 

  def test_google
    @driver.get(@base_url + "/")
    @search.search
  end 

end

class Method

  def search
      @driver.find_element(:id, "gbqfq").clear
      @driver.find_element(:id, "gbqfq").send_keys "this is a test"
      @driver.find_element(:id, "gbqfb").click
      @driver.find_element(:id, "gbqfb").click
  end 

end

我更改了班级名称:

require "test/unit"
require "selenium-webdriver"
require "json"
require "time"


class Google < Test::Unit::TestCase

  def setup
    @driver = Selenium::WebDriver.for :firefox
    @base_url = "https://www.google.com/"
    @accept_next_alert = true
    @driver.manage.timeouts.implicit_wait = 30
    @verification_errors = []
    @search = Suber.new()
  end 

  def teardown
    @driver.quit
    assert_equal [], @verification_errors
  end 

  def test_google
    @driver.get(@base_url + "/")
    @search.search
  end 

end


class Suber


  def search
      @driver.find_element(:id, "gbqfq").clear
      @driver.find_element(:id, "gbqfq").send_keys "this is a test"
      @driver.find_element(:id, "gbqfb").click
      @driver.find_element(:id, "gbqfb").click
  end 


end

现在我不确定如何解决在'Suber'课程中设置@driver的问题.我以为它会起作用,但它会抛出:

NoMethodError:未定义的方法find_element' for nil:NilClass google.rb:37:in搜索'google.rb:25:in`test_google'

:/

Method是Ruby中内置的类(http://ruby-doc.org/core-2.0/Method.html)您必须将类重命名为其他类.
