如何告诉黄瓜和数据库清理器将我的种子数据留在我的rails测试数据库中？

Question

我有几个表，其中包含参数和其他东西，它永远不会改变！

但是，我不能告诉database_cleaner保存这些数据，每次测试之后，它会截断我的所有数据库。

Gems

gem "cucumber-rails", "~> 1.3.0", require: false
gem 'factory_girl_rails'
gem 'database_cleaner'

Config/cucumber.yml

enter code here
<%
rerun = File.file?('rerun.txt') ? IO.read('rerun.txt') : ""
rerun_opts = rerun.to_s.strip.empty? ? "--format #{ENV['CUCUMBER_FORMAT'] || 'progress'}     features" : "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} #{rerun}"
std_opts = "--format #{ENV['CUCUMBER_FORMAT'] || 'pretty'} --strict --tags ~@wip"
%>
default: <%= std_opts %> features
wip: --tags @wip:3 --wip features
rerun: <%= rerun_opts %> --format rerun --out rerun.txt --strict --tags ~@wip

Features/support/env

require 'cucumber/rails'
require 'database_cleaner'
require 'database_cleaner/cucumber'
require 'factory_girl_rails'

Capybara.default_selector = :css
ActionController::Base.allow_rescue = false

begin
  DatabaseCleaner.logger = Rails.logger
  DatabaseCleaner.clean_with(:truncation, :except => %w[regions departements villes positions levels footballtypes genders publicies types])
  DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes positions levels footballtypes genders publicies types]}
rescue NameError
  raise "You need to add database_cleaner to your Gemfile (in the :test group) if you wish to use it."
end

Cucumber::Rails::World.use_transactional_fixtures = false
Before('~@no-txn', '~@selenium', '~@culerity', '~@celerity', '~@javascript') do
  DatabaseCleaner.clean_with(:truncation, :except => %w[regions departements villes positions levels footballtypes genders publicies types])
  DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes positions levels footballtypes genders publicies types]}
end

Before do
  DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes positions levels footballtypes genders publicies types]}
  DatabaseCleaner.clean_with(:truncation, :except => %w[regions departements villes positions levels footballtypes genders publicies types])
  DatabaseCleaner.start
end

After do |scenario|
  DatabaseCleaner.clean_with(:truncation, :except => %w[regions departements villes positions levels footballtypes genders publicies types])
  DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes positions levels footballtypes genders publicies types]}
  DatabaseCleaner.clean
end

你有线索吗？谢谢，纳尔逊

Answer 1

这个问题一直在搜索‘数据库-更干净的黄瓜设置截断种子’，所以，即使这是一个老问题，我将添加这个答案。

对我来说，起作用的是将一个ruby文件添加到功能/支持目录中，内容如下：

Cucumber::Rails::Database.javascript_strategy = :truncation, {:except => %w[regions departements villes]}

(我用你的桌子代替了我的。)您可以将这一行添加到env.rb，但该文件有一个警告不要编辑。显然，在运行黄瓜时，特性/支持目录中的任何.rb文件都会运行。我的是“setup.rb”。

这将重写Cucumber的默认设置，该设置在@javascript标记的场景之后截断整个数据库。

使用版本:黄瓜(1.3.9)，黄瓜-rails (1.4.0)。

也请参阅How do I get cucumber and databasecleaner to leave my seed data in my rails test db?并尝试

DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes]}

见文档中的http://github.com/DatabaseCleaner/database_cleaner#how-to-use。再说一遍，您似乎已经在这样做了。设置Cucumber::Rails::Database.javascript_strategy是在Selenium驱动程序上修复我的javascript测试的额外酱汁。

现在洗干净，把它弄干;)

上面粘贴的代码(env.rb)首先让人困扰的是所有的复制。在使用database_cleaner时，我从来没有这样做过。如果将文件简化为以下内容会发生什么情况：

require 'cucumber/rails'
require 'database_cleaner'
require 'database_cleaner/cucumber'
require 'factory_girl_rails'

Capybara.default_selector = :css
ActionController::Base.allow_rescue = false
Cucumber::Rails::World.use_transactional_fixtures = false


DatabaseCleaner.logger = Rails.logger
DatabaseCleaner.strategy = :truncation, {:except => %w[regions departements villes positions levels footballtypes genders publicies types]}

Before do
  DatabaseCleaner.start
end

After do |scenario|
  DatabaseCleaner.clean
end

这更接近我过去所做的和我所看到的工作。
