我刚开始接触TDD,现在我的测试出现了一些Rspec错误。在运行后,我的某些测试中会出现undefined method 'visit'
的错误。希望能得到帮助,让这些测试通过。谢谢。

最后是我的 views/users/new.html.erb 文件。
<% provide(:title, 'Sign up') %>
<h1>Sign up</h1>
<p>Find me in app/views/users/new.html.erb</p>
and views/users/show.html.erb
<% provide(:title, @user.name) %>
<h1><%= @user.name %></h1>
& 我已添加了我的 UsersController
class UsersController < ApplicationController
def new
end
def show
@user = User.find(params[:id])
end
end
根据Billy的解决方案修复后,现在出现了这个新错误。
