Question

I’m trying to get rspec to start working again. When I go to test anything, I get the following:

stacyrandel$ bundle exec rspec spec/requests/static_pages_spec.rb

Answer 1

Have a look into your source file /Users/stacyrandel/rails_projects/callred/app/models/user.rb line 21, make sure that uniqueness is used in proper context according to this tutorial: http://guides.rubyonrails.org/active_record_validations_callbacks.html#uniqueness

As pointed out by @dpassage in the other answer there are differences between ruby versions:

1. Ruby 1.8.7:

   validates :email, :uniqueness => true
   

2. Ruby 1.9+:

   validates :email, uniqueness: true
   

But your stacktrace shows that ruby 1.9.3 was used, so it should be fine.
