Question

我正在努力让以下工作。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。我认为它会起作用，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：在`test_google'

中

Answer 1

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

Answer 2

根据您的编辑，请执行以下操作：

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

module 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

class Google < Test::Unit::TestCase

  include Suber

  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
  end 

end

这真的不是一个解决方案，但是如果你有时间，那么Metaprogramming Ruby这本书就会详细介绍类。

Ruby初学者试图从Ruby中的另一个类调用一个方法？
