Question

问题仍存在于Rails 4.2和最新的水豚身上。

我认为这不是特定于驱动程序的问题，因为它使用rack_test，capybara-webkit甚至是poltgeist都会变慢。

渲染大约需要78086ms。

示例日志输出：

TransitionKeys是fast_gettext的东西。 MenuItems是一个单元格（单元格宝石）。

我使用以下宝石进行测试：

group :test do
  gem 'factory_girl_rails'
  gem 'mocha'
  gem 'shoulda'
  gem 'database_cleaner'
  gem "minitest-rails-capybara"
  gem 'capybara-email'
  gem 'capybara-webkit'
  gem 'poltergeist'
  gem 'cucumber-rails', :require => false
end

我也尝试过更改事务和截断策略。

怎么了？

修改

当我启动本地服务器时： RAILS_ENV =测试捆绑执行轨道c
即使config.assets.debug = false

，它也很慢

Answer 1

如果这只发生在第一次运行的测试中，那么这与Capybara无关，很可能是编译资产的资产管道。您可以在运行测试之前尝试在测试环境中对它们进行预编译，看看是否加快了测试速度。

Answer 2

确保在相关的config.assets.debug = false文件中设置了config/environments/*.rb（可能只是test.rb）。

Capybara慢速测试，视图渲染需要花费大量时间
