The test suite fails

Problem

After fixing Rakefile (see #4 and the corresponding issue #3) the test suite fails:

$ rake
/Users/grn/.rbenv/versions/2.1.5/bin/ruby -S rspec ./spec/handshake_spec.rb
Warning: you should require 'minitest/autorun' instead.
Warning: or add 'gem "minitest"' before 'require "minitest/autorun"'

The output indicates at least three problems:

1. a problem with Minitest in handshake.rb
2. warnings about overriding object_id (reported in redefining `object_id' may cause serious problems #2) and __send__
3. 7 failing test cases
