# Running a single minimalistic unit test with Rails 4 and Ruby 2.1.1 is a lot faster
# if you avoid loading Rails:

# Running the test *with* Rails

time ruby -Itest test/models/my_model_test.rb # => real ~ 6s

# Running the test *without* Rails

time ruby -Itest/no_rails test/models/my_model_test.rb # => real ~ 0.6s
