异常消息: rails应用程序中没有要加载的此类文件

Question

我已经在我的rails应用程序中包含了test下的test_helper.rb。我甚至在我的test->unit下的test.rb文件中包含了require 'test_helper'。当我在RubyMine中为应用程序运行所有测试时，我得到以下错误：

我有最新版本的RubyMine 3.2，Ruby1.9.2p290和Rails 3.1.0。

我遗漏了什么？谢谢!

Answer 1

test_helper.rb位于测试目录中。您正在从根目录运行测试，这意味着文件的路径是错误的。尝试从test目录运行测试。

如果您想要从根目录运行您的测试，那么您必须将其更改为require File.join(File.dirname(__FILE__), '..', 'test_helper.rb')，其中file是包含该行的文件(您的测试用例)的路径，其余的是test_helper.rb相对于该文件的路径。这样，在哪里运行测试就变得无关紧要了。

Answer 2

在我的情况下(rm7.1/ Win7 / Rails 3.0)，我必须执行以下操作：

在“-Itest参数”的开头添加"Ruby“

注意:将工作目录更改为'test‘对我不起作用。
