ruby-on-rails - WebMock.disable_net_connect!不工作

Question

我正在尝试编写一个基于 WebMock 的测试用例来模拟调用 http API。为此，我将 webmock/rspec 包含在我的 spec_helper.rb 文件中，还添加了 WebMock.disable_net_connect!(allow_localhost: true) 以禁止网络上的 http 请求。但是当我运行一个虚拟测试来检查 http 请求是否被阻止时，我可以看到 http 请求仍在进行中。

spec_helper.rb 文件:

ENV["RAILS_ENV"] ||= 'test'
require 'rubygems'
require File.expand_path("../../config/environment", __FILE__)
require 'authlogic/test_case'
include Authlogic::TestCase
require 'rspec/rails'
require 'rspec/autorun'
require 'rspec/mocks'
require 'capybara/rspec'
require 'capybara/rails'
require "paperclip/matchers"
require 'vcr'
require 'webmock/rspec'
WebMock.disable_net_connect!
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}
RSpec.configure do |config|
  config.treat_symbols_as_metadata_keys_with_true_values = true
  config.mock_with :rspec
  config.use_transactional_fixtures = false

  config.fixture_path = "#{::Rails.root}/spec/fixtures"
  config.include Paperclip::Shoulda::Matchers

  config.include FactoryGirl::Syntax::Methods

  config.infer_base_class_for_anonymous_controllers = false
  config.include Rails.application.routes.url_helpers
  config.include Capybara::DSL
  config.render_views
  config.filter_run focus: true
  config.run_all_when_everything_filtered = true

end
VCR.configure do |c|
  c.cassette_library_dir = 'spec/vcr_cassettes'
  c.hook_into :webmock
  c.allow_http_connections_when_no_cassette = true
end

ActiveSupport::Dependencies.clear

还有我写的虚拟测试文件:

require 'spec_helper'  
describe 'External request' do
    it 'queries FactoryGirl contributors on GitHub' do
      uri = URI('https://api.github.com/repos/thoughtbot/factory_girl/contributors')

      response = Net::HTTP.get(uri)

      expect(response).to be_an_instance_of(String)
    end
  end

请帮助我找出是否缺少某些配置或者我正在做的其他事情。

Answer 1

发现问题出在 VCR 配置中的以下配置:

c.allow_http_connections_when_no_cassette = true

将其转换为 false 解决了问题，因为 VCR 配置覆盖了 webmock 配置，因为我已经定义了 c.hook_into :webmock 。
