異常消息：沒有這樣的文件加載在rails應用程序

Question

我在我的rails應用程序中包含test_helper.rb在test下。我甚至在test->unit的test.rb文件中包含了 require 'test_helper'。當我在應用程序的RubyMine中運行所有測試時，出現以下錯誤：

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

我在想什麼？ 謝謝！

Answer 1

test_helper.rb位於測試目錄中。您正在從根目錄運行測試，這意味着該文件的路徑是錯誤的。嘗試從測試目錄運行測試。

如果要從根目錄運行測試，則必須將其更改爲require File.join(File.dirname(__FILE__), '..', 'test_helper.rb')，其中FILE是包含此行（您的測試用例）的文件的路徑，其餘爲test_helper.rb，相對於該文件。這樣，你從哪裏運行測試就無關緊要了。

Answer 2

在我的情況（RM 7.1/Win7的/ Rails的3.0），我必須做到以下幾點：

Add "-Itest" at the beginning of "Ruby arguments"

注意：改變工作目錄 '測試' 並沒有爲我工作。
