我使用Mongoid作为我的数据库并按照其他Stackoverflow问题的指示配置了我的spec_helper.rb
文件,但是我仍然在后续测试中收到对象存在的错误。因此,database_cleaner
并不是应该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
我在第一次运行时(在我手动重置数据库之后)使用rake db:reset RAILS_ENV=test
获得的输出正常,但是在我得到之后每次运行:
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?
答案 0 :(得分:4)
好吧,经过更多的阅读后,我来确定database_cleaner和Mongo一起玩不好。虽然它可能不是最干净的解决方案,但很简单:
在我的spec_helper.rb
文件中,我最终将此行添加到RSpec.configure
块:
config.after(:each) do
Mongoid.purge!
end
