Rspec无法运行：在connection_for中进行救援：连接被拒绝：localhost：7475（法拉第：: ConnectionFailed）

Question

我一直在忽略我的rspec测试，但是试图重新获得它，现在我无法运行基本的rspec。

我正在使用neo4j宝石，Figaro宝石，考拉宝石和faceook-omniauth宝石。 自上次工作以来，这些就是我的补充。

如果您需要参考我项目的任何领域，请告诉我，因为我不确定要去哪里找

Answer 1

您已将Neo4j测试环境配置为在端口7475上运行，这是一个好主意。

• 安装： rake neo4j:install[community-2.1.5,test]
• 设置端口： rake neo4j:config[test,7475]
• 启动服务器： rake neo4j:start[test]
• 停止服务器： rake neo4j:stop[test]但您可能已经猜到了。 ;-)

如果将来需要参考，请访问https://github.com/neo4jrb/neo4j/wiki/How-To-Test进行概述。 还要确保运行bundle update neo4j ，您落后了两个更新。
