所以我是 TDD 的新手，我在测试中抛出了一些 Rspec 错误......基本上在运行 bundle exec rspec spec 之后，我的undefined method 'visit'一些规范出现错误。任何有关如何使这些测试通过的帮助将不胜感激：谢谢。

我的规范/请求/user_pages_spec.rb
require 'spec_helper'

还有我的 spec/models/user_spec.rb
require 'spec_helper'

end
end
最后是我的意见/用户/new.html.erb
<% provide(:title, 'Sign up') %>
<h1>Sign up</h1>
<p>Find me in app/views/users/new.html.erb</p>
和意见/用户/show.html.erb
<% provide(:title, @user.name) %>
<h1><%= @user.name %></h1>
& 我已经添加了我的用户控制器
class UsersController < ApplicationController
def new
end
def show
@user = User.find(params[:id])
end
end
在按照比利的解决方案进行修复后，现在也出现了这个新错误
