Ruby on rails 在utility.rb中注册实用程序测试方法的调用失败

我对在Rails上编写测试有点陌生，现在我正在学习RoR教程。我正在尝试添加我自己的测试实用程序方法sign_up，类似于utility.rb中已有的sign_in方法。但是，当在我的注册页面上调用它时，我遇到以下错误：

2) User pages index pagination as an admin user to unlock new users 
     Failure/Error: sign_up user
     Capybara::ElementNotFound:
       cannot fill in, no text field, text area or password field with id, name, or label 'Name' found
     # (eval):2:in `fill_in'
     # ./spec/support/utilities.rb:33:in `sign_up'
     # ./spec/requests/user_pages_spec.rb:63:in `block (5 levels) in <top (required)>'

它似乎开始出错，甚至只是访问注册路径-我甚至不确定它会去那里。此外，如果我注释掉

fill\u in“Name”

行，它将以同样的方式阻塞

fill\u in“Email”

行

如果您对这里发生的事情有任何建议或想法，我们将不胜感激

谢谢，

使用工厂创建用户时，它会将其插入数据库中。因此，当您转到注册页面并尝试使用该用户时，它已经存在，您将被重定向到主页。这意味着不存在可用于填充的字段。简化规格：

require 'spec_helper'

describe "signup page" do
  subject { page }

  describe "with valid information" do
    before { sign_up('em', 'em@em.com', '123456') }
    it { should have_title_and_h1('em') }
  end
end

实用方法：

def sign_up(name, email, password)
  visit signup_path
  fill_in "Name",         with: name
  fill_in "Email",        with: email
  fill_in "Password",     with: password
  fill_in "Confirmation", with: password
  click_button "Create my account"
end

将通过浏览器界面创建用户

def sign_up(name, email, password)
  visit signup_path
  fill_in "Name",         with: name
  fill_in "Email",        with: email
  fill_in "Password",     with: password
  fill_in "Confirmation", with: password
  click_button "Create my account"
end
