我想测试使用MINITEST和webrat红宝石认证应用程序，但出现错误。

像测试visit '/'失败，错误Status 200 expected but was 404.

含像代码测试fill_in :email, :with => "first@company.com"失败，错误Could not find field: :email 。

我看了几西纳特拉，测试和webrat文件和论坛。他们中的一些老建议的东西一样西纳特拉::默认设置，但github.com/brynary/webrat/wiki/sinatra ，构建西纳特拉应用驱动下Webrat测试和学习从大师：西纳特拉内幕是新的，但他们仍然会失败。

基本上，我不喜欢RSpec的，黄瓜等句子的语法，但做想做的事的行为驱动开发。我真的很喜欢MINITEST语法，这两个测试和输出，这就是为什么我选择BDD webrat。如果我错了期待webrat履行验收测试的需求，请直接告诉我，我应该用这个框架或那一个。

除此之外，主文件和测试文件的第一部分如下。我希望有人能解释我，我很想念？

test_file里面

require "test/unit"
require "minitest/autorun"
require "rack/test"
require 'webrat'
require_relative "../lib/kimsin.rb"

Webrat.configure do |config|
  config.mode = :rack
end

ENV["RACK_ENV"] = "test"

class KimsinTests < Test::Unit::TestCase
  include Rack::Test::Methods
  include Webrat::Methods
  include Webrat::Matchers

  def app
    Sinatra::Application.new
  end

  def test_create_user
    visit "/user/new"
    fill_in :username, :with => "first@company.com"
    fill_in :password, :with => "abC123?*"
    fill_in :confirm_password, :with => "abC123?*"
    click_link "Register"
    assert 201, last_response.status, "Status 201 expected but was #{last_response.status}.\n#{error}"
    assert_contain /Logged in as first@company.com./, "No user created"
    assert_contain /Logout/, "Logout link not present"
  end

main_file

require "sinatra"
require "erb"
require_relative "../lib/kimsin/version"
require_relative "../lib/kimsin/user"

class Kimsin < Sinatra::Application
  use Rack::Session::Pool, :expire_after => 2592000
  set :session_secret, BCrypt::Engine.generate_salt

  configure :development do  
    DataMapper.auto_migrate!  
  end

  get "/" do
    if session[:user_id]
      user = User.get session[:user_id]
      email = user.email
      erb :index, :locals => { :email => email }
    else
      email = nil
      erb :index, :locals => { :email => email }
    end      
  end

使用西纳特拉与Webrat应该正常工作。我认为，您看到的错误是（在你的测试文件围绕第18行）下面的方法引起的：
