exception消息：在rails应用程序中没有要加载此类文件

我在rails应用程序中包含了test_helper.rb 。 我甚至在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，我收到以下错误：

我有所有RubyMine 3.2，ruby 1.9.2p290和Rails 3.1.0的最新版本。

我错过了什么？ 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，这意味着该文件的路径是错误的。 尝试从测试目录运行测试。

如果要从根目录运行测试，则必须将其更改为require File.join(File.dirname(__FILE__), '..', 'test_helper.rb') FILE require File.join(File.dirname(__FILE__), '..', 'test_helper.rb') ，其中FILE是指向包含此行的文件（您的测试用例），其余是相对于该文件的test_helper.rb的路径。 这样，运行测试的地方就无关紧要了。

Answer 2

在我的情况下（RM 7.1 / Win7 / Rails 3.0），我必须做以下事情：

在“Ruby参数”的开头添加“-Itest”

注意：将工作目录更改为“test”对我来说不起作用。
