为我在 rails 3 中进行集成测试的方法提供帮助

Question

我正在为我的 rails 3.2.16 应用程序准备一些集成测试，我认为在我的用户场景中，我有几个调用会在许多测试中重复，所以我想通过放置它们来干燥它们在单独的公共模块中，

例如我创建了/test/integration/my_test_helpers.rb：

require 'test_helper'

module MyTestHelper

  def login_user(email, password, stay = 0)
    login_data = {
      email: email,
      password: password,
      remember_me: stay
    }
    post "/users/sign_in", user: login_data
    assert_redirected_to :user_root
  end
end

并尝试在我的集成测试中使用它：

require 'test_helper'
require "./my_test_helpers.rb"

class CreateCommentTest < ActionDispatch::IntegrationTest

  setup do
    @user = users(:user1)
  end

  test "create comment" do
    login_user @user.email, "password", 1
  end
end

我得到异常：

`require': cannot load such file -- ./my_test_helpers.rb (LoadError)

如何加载模块？把MyTestHelpers做成一个模块对吗？

Answer 1

你应该把你的助手放在支持文件夹（test/support/my_test_helpers.rb，或其他东西）并在test_helper.rb中加载模块：

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

require_relative "./support/my_test_helpers"

require "minitest/rails"

class ActiveSupport::TestCase
  ActiveRecord::Migration.check_pending!

  fixtures :all

  # Add more helper methods to be used by all tests here...
end

不记得include你的模块：

require 'test_helper'

class CreateCommentTest < ActionDispatch::IntegrationTest
  include MyTestHelper

  setup do
    @user = users(:user1)
  end

  test "create comment" do
    login_user @user.email, "password", 1
  end
end
