Rails 4 Rspec Capybara：提取通用测试功能到 Ruby 模块不工作

Question

我想从我的功能测试中提取 sign_in 到 Ruby 模块中，与此 Thoughtbot article 一致。功能未看到 sign_in。我做错了什么？

Failures:
  1) User signs in with valid email and password
     Failure/Error: sign_in
     NameError:
       undefined local variable or method `sign_in' for #<RSpec::ExampleGroups::UserSignsIn:0x0000000238a958>
     # ./spec/features/sign_in_spec.rb:16:in `block (2 levels) in <top (required)>'
     # .bundle/binstubs/rspec:16:in `load'
     # .bundle/binstubs/rspec:16:in `<main>'

你的 rails_helper.rb 或 spec_helper.rb 中有什么东西会导致你的助手被加载吗？

将您的 rails_helper.rb 改为：

ENV['RAILS_ENV'] ||= 'test'
require File.expand_path('../../config/environment', __FILE__)

abort("The Rails environment is running in production mode!") if Rails.env.production?

require 'spec_helper'
require 'rspec/rails'
require 'pry'
require 'faker'
require 'devise'
require 'email_spec'

Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }

ActiveRecord::Migration.maintain_test_schema!

RSpec.configure do |config|
    config.include Features::SessionHelpers, type: :feature
...

并删除spec/support/features.rb。这将确保执行顺序正确，创建您的助手模块（以及 support 文件夹中的任何其他内容），然后将助手包含在 RSpec 的命名空间中。
