RSpec test not passing for validating uniqueness of email in spec/models/contact_spec.rb

[trekr5]

Hello,

Can someone please help?

I've created the rspec test for validating uniqueness of email in spec/models/contact_spec.rb and run it (exactly the way it's done in everydayrails) and it isn't passing.

I get the following error:
ArgumentError: Unknown validator: 'UniquesnessValidator'

I'm running rails 4.0.3, rspec 2.14.8 and ruby 2.1.0
