'uninitialized constant Cell::TestCase' when running auto-generated tests in Rails 3.1.0.rc5 about cells HOT 3 CLOSED

We removed the explicit require in the cells railtie, see here: #57

from cells.

Ok. So it seems that Cell::TestCase does not get automatically loaded by Test::Unit after all. That's because lib/ directories from engines and railties are not added by Rails to config.autoload_paths automatically. I wonder why is it autoloaded by rspec-cells. Maybe it requires it explicitly?

So I think that CHANGELOG and README should be updated to say that when using Test::Unit you need to put require 'cell/test_case' in test_helper.rb. Or you could make cells add its lib/ to config.autoload_paths. It would probably be something like this:

# lib/cells/railtie.rb
initializer 'cells.add_autoload_paths', :before => :set_autoload_paths do |app|
  app.config.autoload_paths << File.expand_path("../../lib", File.dirname(__FILE__))
end

UPDATE: Since I made that change anyway to see if it works, here's a patch in case you wanted to use this: #72

from cells.
