Hi!

When building a Debian package from your gem, I noticed that I could not run the tests because of missing code in the test directory, namely:

• test_helper.rb file (I got it from the Github repo, and removed some stuff unrelated to bson)
• a require 'rbconfig' in test/bson/bson_test.rb
• the code for the to_bson_code method for String objects

Moreover, I got error about undefined classes when using
require 'active_support/multibyte/chars'
in test/bson/bson_tests.rb. Replacing it with simply
require 'active_support'
solved the problem.

Thank you!

Cheers,

Cédric
