I have included test_helper.rb under test in my rails application. I have even included
require 'test_helper' in my test.rb files under test->unit. When I run all the test in RubyMine for the application, I get the following error:
I have the latest versions of all RubyMine 3.2, ruby 1.9.2p290 and Rails 3.1.0.

What am I missing? Thanks!
test_helper.rb is located within the test directory. You are running the tests from the root directory, which means the path to the file is wrong. Try running your tests from the test directory.
If you want to run your tests from the root directory, you would have to change this to require File.join(File.dirname(__FILE__), '..', 'test_helper.rb'), where FILE is the path to the file that contains this line (your test case), and the rest is the path of test_helper.rb, relative to that file. This way, where you run the test from is irrelevant.
In my situation (RM 7.1 / Win7 / Rails 3.0), I had to do the following:
Add "-Itest" at the beginning of "Ruby arguments"
Note: Changing the working directory to 'test' didn't work for me.
