Ruby 加载带有RSpec的ActiveRecord固定装置（无导轨）

我正在使用一些

ActiveRecord

模型，这些模型在

Rails

之外，我正在为它们编写单元测试。在我的测试中，我希望能够使用夹具，并认为我会为此使用一些功能。我不能简单地使用

require“rspec-rails”

，因为它有一些rails依赖项，而我没有使用rails

以下是我正在使用的

spec\u帮助程序

：

require 'active_record'
require 'active_record/fixtures'
require 'active_support'
require 'rspec/rails/extensions/active_record/base'
require 'rspec/rails/adapters'
require 'rspec/rails/fixture_support'  # Includes ActiveRecord::TestFixtures
                                       # into the RSpec config

require 'my_models'

# Setup database connection
environment = "test"
configuration = YAML::load(File.open('config/database.yml'))
ActiveRecord::Base.establish_connection(configuration[environment])

RSpec.configure do |config|
  config.fixture_path = File.expand_path("../../test/fixtures", __FILE__)

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"

  # Run each test inside a DB transaction
  config.around(:each) do |test|
    ActiveRecord::Base.transaction do
      test.run
      raise ActiveRecord::Rollback
    end
  end
end

这是一个测试的例子

require 'spec_helper'

describe Transaction do

  before :each do
    self.class.fixtures :users, :merchants
  end

  it "should do this and that" do
    ...
  end
end

问题是，通过这种方式，夹具没有加载。我查看了

rspec rails

代码，但无法确定应该扩展哪个模块或调用哪个方法。

在深入研究活动记录代码之后，我发现没有加载夹具的原因是因为我没有设置

ActiveRecord:：Base.configurations

。以下内容解决了该问题：

configuration = YAML::load(File.open('config/database.yml'))
ActiveRecord::Base.configurations = configuration
