Question

我有一个我一直在使用ruby 1.9.1的应用程序。我想在我的UI中测试javascript，而capybara的默认selenium驱动程序不支持我需要测试的事件。

所以我正在经历使用rvm将应用程序切换到jruby进行测试的过程，因为显然celertiy / culerity目前仅适用于jruby。我已经安装了我的软件包，应用程序似乎在jruby上正常工作，但是当我尝试运行'rake cucumber'时，我得到以下输出：

有一次我使用sqlite作为我的测试数据库，但后来改变了。我甚至尝试过改回sqlite，但仍然得到同样的错误。如果我在features / support / env.rb中禁用了database_cleaner，那么测试会运行，但它们都会神秘地失败。

任何人都知道这里发生了什么？

Answer 1

看来这是数据库清理器和jdbc交互方式的问题。

http://github.com/tmikoss/database_cleaner/commit/83d85cf7740e4aef97dd6fd5c0908cb09a2f0ca9

更新：我找到了这个问题，因为我正在努力解决同样的问题。我上面链接的database_cleaner版本确实解决了这个问题，database_cleaner项目上存在一个问题，它也会通知团队这个问题。我暂时能够绕过它：

# someplace on your computer    
git clone http://github.com/tmikoss/database_cleaner.git

#in your projects Gemfile
gem "database_cleaner", :path => "path/to/above/copy/of/gem"

更新更新：此修复程序应该在database_cleaner master

的v0.6.0上提供

您是否检查过您使用的SQLite适配器是否与jRuby兼容？您需要以下内容：

宝石：activerecord-jdbcsqlite3-adapter和jdbc-sqlite3

（我总是安装两者，你可能只使用activerecord-jdbcsqlite3-adapter）

然后编辑config/database.yml以使用jdbcsqlite3适配器：

cucumber:
  adapter: jdbcsqlite3
  database: db/development.sqlite3
  timeout: 5000

使用mysql在Jruby on Rails应用程序上使用Cucumber / capybara / celerity运行集成测试
