数据库清理程序与黄瓜轨道

问题描述

我正在为注册表单写一个场景。

I am writing a scenario for signup form.

     @abc

     @selenium

     Scenario:Non registered user signs up
        Given I am on the sign-up page
        When I fill in the following:
          |first_name|Anidhya|
          |last_name|Ahuja|
          |email|[email protected]|
          |password|123456|
        And I press "submit"
        Then I should see "Registration complete"

我想在这种情况后使用数据库清理器回滚测试数据库，以便我可以一次又一次地使用这个场景。

对于env.rb文件我写道：

I want to use database cleaner to roll back the test database after this scenario so that I can use this scenario again and again.

For that inside my env.rb file I wrote:

begin
  require 'database_cleaner'
  require 'database_cleaner/cucumber'
  DatabaseCleaner.strategy = :transaction

  Cucumber::Rails::World.use_transactional_fixtures = true

rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end


Before('@abc') do
  DatabaseCleaner.start
end
After('@abc') do
  DatabaseCleaner.clean
end

现在当我运行场景时，用户被保存在数据库中，并且数据库清理器失败。我没有看到任何错误讯息

• 请澄清如何使用数据库清理器只有一个场景。
  
• 此外，您还可以提供使用截断和事务之间的重要区别。我认为截断会清除整个数据库，但是
>

• Could you please clarify how to use database cleaner for only one scenario.I only want to use cleaner for this scenario.
• Also could you please also provide the vital difference between using truncation and transaction.I think truncation clears the whole database but I dont want that.
• Is there a better method of doing signup testing than this?

推荐答案

您无法使用selenium运行事务，因为测试运行在应用程序AFAIK的两个单独实例上

You can't run transactions with selenium because the test runs on two separate instances of the app AFAIK
