I get the following error when I run my Rails application in production mode, but when I run my app in development mode it works fine. Can I use any gems in production mode?
`require': No such file to load -- test_helper (LoadError) The following is the full trace of the code:

You have a test, quarterly_export_statement_test.rb, in your app/controllers directory.
In production, Rails loads all classes eagerly, so it attempts to load your test. Your test does require 'test_helper'. The test directory, which contains test_helper, isn't in the load path in the production environment (good!), so that require fails.
To fix the problem, move the test to the test directory where it belongs, which appears to be /home/nyros/Documents/Projects/DFL/Working/DFL/test.
