Database_cleaner gem 不清理

God*_*a74 1 ruby rspec ruby-on-rails mongodb

我使用 Mongoid 作为我的数据库,并spec_helper.rb按照其他 Stackoverflow 问题的说明配置了我的文件,但是我仍然收到一个错误,即在后续测试中存在对象。所以,database_cleaner没有像它应该的那样清理我的测试数据库。

这是我的spec_helper.rb

ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rails/mongoid'
require 'mongoid-rspec'
require 'database_cleaner'

Mongoid.load!(Rails.root.join("config", "mongoid.yml"))

# Load support files
Dir["#{File.dirname(__FILE__)}/support/**/*.rb"].each { |f| require f }
RSpec.configure do |config|
  config.mock_with :rspec
  #config.use_transactional_fixtures = true
  config.infer_base_class_for_anonymous_controllers = false
  config.order = "random"

  config.before(:suite) do
    DatabaseCleaner[:mongoid].strategy = :truncation
    DatabaseCleaner[:mongoid].clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

我的 rspec 测试文件很简单:

describe Stock do
  it "should get created with only name and symbol" do
    stock = Stock.create(name: "Netflix", symbol: "NFLX")
    expect(stock.errors.full_messages).to eq []
  end
end

我得到的输出在第一次运行时很好(在我手动重置数据库之后),rake db:reset RAILS_ENV=test但是之后的每次运行我都会得到:

Failures:

  1) Stock should get created with only name and symbol
     Failure/Error: expect(stock.errors.full_messages).to eq []

       expected: []
            got: ["Symbol is already taken"]

       (compared using ==)
     # ./spec/models/stock_spec.rb:6:in `block (2 levels) in <top (required)>'

我错过了什么?

好吧,经过大量阅读后,我确定 database_cleaner 和 Mongo 不能很好地协同工作。虽然它可能不是最干净的解决方案,但它很简单:

在我的spec_helper.rb文件中,我最终将此行添加到RSpec.configure块中:

config.after(:each) do
  Mongoid.purge!
end
