当我已经定义了方法时，出现“ NoMethodError”

Question

编写我的Ruby-Watir-黄瓜bdd测试，我得到了：

NoMethodError: undefined method `msg=' for #<Watir::Browser:0x0000558fbcdc0cc0>
./features/support/pages/message_page.rb:27:in `escribir'
./features/step_definitions/message_steps.rb:14:in `/^I'm able to write and send a "([^"]*)" successfully$/'
./features/send_messages.feature:12:in `Then I'm able to write and send a "Robot message" successfully'
./features/send_messages.feature:9:in `Then I'm able to write and send a "<message>" successfully'
1 scenario (1 failed)
4 steps (1 failed, 3 passed)
0m12.939s

Process finished with exit code 1

当我已经定义了方法时：

class MessagePage
  include PageObject
  @@browser = Watir::Browser.new
  page_url 'https://www.linkedin.com/messaging/'
  text_field(:searchcontact, name: 'searchTerm')
  div(:txtmessage,:role => "textbox")
  button(:btnsend,:type => 'submit')
  div(:txtfield,:xpath =>"//div//div[@role='textbox']")
  text_field(:mensaje,:xpath =>"//div//div[@role='textbox']")
  div(:msg,:role => "textbox") /// HERE!!!

  def searchcontact contact
    self.searchcontact = contact
    #searchcontact(contact).send_keys(:enter)
    wait 5
  end

  def buscar contact
    wait_until do
      searchcontact_element.visible?
      self.searchcontact = contact
    end
    self.searchcontact = contact
  end

  def escribir (message)
    self.msg = message
    wait 5
  end

  def writemessage message
    wait_until do
      msg_element.visible?
      self.msg = message
    end
    self.msg = message
  end

  def sendmessage
    btnsend
  end



end

Answer 1

访问器div(:msg,:role => "textbox")不会生成#msg=方法。它仅定义：

#msg-获取div的文本
• #msg?-检查div是否存在
• #msg_element-获取PageObject :: Elements :: Element

您将需要手动定义方法或为内容可编辑元素创建小部件。

Answer 2

单击文本框后，您可以向其发送密钥。所以像

msg.click然后msg.send_keys（'blah'）

或者也许是文本框，您可以根据页面的编码方式直接对其进行操作-因此msg.send_keys（'blah'）可能直接起作用。
