我目前正在尝试将Spotify Web API集成到我的Ruby on Rails应用程序中。目前我正在尝试使用Capybara通过登录程序指导我的功能测试。我的测试目前看起来像这样：
require 'rails_helper'
feature 'visiting homepage' do
it 'Allows the user to log on with Spotify' do
visit('/')
click_on('Sign in with Spotify')
# expect(page).to have_content("Type in an artist, genre or mood and we'll do the rest")
end
end
意识到我需要模拟omniauth的身份验证流程，我遵循本教程的建议（https://github.com/omniauth/omniauth/wiki/Integration-Testing），这建议我将OmniAuth.config.test_mode = true添加到我的测试中，以便“所有请求OmniAuth将被短路以使用模拟身份验证哈希，如下所述。对/ auth / provider的请求将立即重定向到/ auth / provider / callback。“所以我把这一行放在rails_helper.rb
require 'spec_helper'
ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)
# Prevent database truncation if the environment is production
abort("The Rails environment is running in production mode!") if Rails.env.production?
require 'rspec/rails'
require 'capybara/rspec'
require 'capybara/rails'
OmniAuth.config.test_mode = true
OmniAuth.config.mock_auth[:spotify] = OmniAuth::AuthHash.new({
:provider => 'spotify',
:uid => '123545'
})
然后，我将重定向路由添加到Spotify Web API应用程序仪表板上的设置，并在config/routes.rb
get '/auth/spotify/callback'
然而，完成所有这些后，我收到以下错误：
Failures:
1) visiting homepage Allows the user to log on with Spotify
Failure/Error: click_on('Sign in with Spotify')

我试图阅读并理解omniauth的strategy.rb中的代码，但是，我找不到错误提及的未定义Auth变量。
