为我的Rails集成测试方法提供帮助3

Question

I'm preparing some integration tests on my rails 3.2.16 application, I figured that, in my user scenarios, I have several calls that I repeat over many tests, so I would like to DRY them up, by placing them in a separate common module,

for example I have created /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

and tried to use it in my integration test:

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

I get exception:

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

How can I load the module? is it right to make MyTestHelpers a module?

You should put your helper in support folder( test/support/my_test_helpers.rb , or something) and load module in test_helper.rb :

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

Do not remember include your module:

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
