如何使用rails配置database_cleaner

我在我的app/services文件夹中有一些服务。现在我想测试这些服务，所以我使用rspec和factorygirl。我与factoryGirl创建用户，但是当我运行rspec的它显示我以下错误如何使用rails配置database_cleaner

Failure/Error: @user ||= FactoryGirl.create(:user) 

ActiveRecord::RecordInvalid: 
    Validation failed: Email has already been taken

我使用database_cleaner宝石清洁每次测试后的数据库。下面是我的配置文件

ENV['RAILS_ENV'] ||= 'test' 
require File.expand_path('../../config/environment', __FILE__) 
abort("The Rails environment is running in production mode!") if Rails.env.production? 

require 'spec_helper' 
require 'rspec/rails' 
require 'factory_girl_rails' 
require 'database_cleaner 
ActiveRecord::Migration.maintain_test_schema! 

RSpec.configure do |config| 

    config.include FactoryGirl::Syntax::Methods 

    config.fixture_path = "#{::Rails.root}/spec/fixtures" 
    config.include Devise::TestHelpers, type: :controller 

    config.use_transactional_fixtures = false 

    config.before(:suite) do 
    DatabaseCleaner.strategy = :transaction 
    DatabaseCleaner.clean_with(:truncation) 
    end 

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

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


    config.infer_spec_type_from_file_location! 
    config.filter_rails_from_backtrace! 

end

我不知道我要去的地方错了。

你确定你是不是要一个简单的例子中创建2个用户使用相同的电子邮件？ –

你需要指定每个规格（事务这里是一个安全的选择）之间使用的策略：

RSpec.configure do |config| 
    config.before(:suite) do 
    DatabaseCleaner.clean_with(:truncation) 
    end 

    config.before(:each) do 
    DatabaseCleaner.strategy = :transaction 
    end 

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

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