Stuck on write our first tests

I'm having trouble with a no method error and I have no clue what is causing it. Any clues?

Do you have any deprecation warnings when you run rspec?

When I try to run it it just throws me this error.

My guess is you installed rspec 3 which had some changes.

Try 

require 'rails_helper'

instead of 

require 'spec_helper'

I feel like I have a lot of corrupted files because I've had a lot of errors just trying to fix this one. Is there a way to make my machine forget I ever had rails and reinstall everything from scratch, I've only been doing this about 7 months.

Can you please check if you have these lines in your Gemfile?

group :development, :test do
    gem "rspec-rails", '~> 2.0'
end

also check if you have

config.infer_spec_type_from_file_location!

line in your spec_helper.rb
