Rspec for Rails

Rspec within Rails

i.e. RAILS_ENV = (development, test, production)

Gemfile:

gem "rspec-rails", :group => [:test, :development]
gem 'jquery-rails'


development:
  adapter: postgresql
  encoding: unicode
  database: <%= File.basename(Rails.root) %>_development
  pool: 5
  host: localhost
  username:  <%= ENV['PG_USERNAME'] %>
  password:

test:
  adapter: postgresql
  encoding: unicode
  database: <%= File.basename(Rails.root) %>_test
  pool: 5
  host: localhost
  username: <%= ENV['PG_USERNAME'] %>
  password:

production:
  adapter: postgresql
  encoding: unicode
  database: <%= File.basename(Rails.root) %>_production
  pool: 5
  username: <%= ENV['PG_USERNAME'] %>
  password:
  
command prompt:
  rails g rspec:install

$ rails g model trainer email:string password_digest:string name:string
$ rake db:migrate
$ RAILS_ENV=test rake db:migrate //creates the table just in the test... rake db:migrate just installs on developement.

Describe and context are kind of the same, but they differ in when they use them for human readability.
Inside Describe, you have contexts which are the state.
This is a good place to use the 'let' variable.
Describe is at the top of the file and for methods.

use Let instead of before to instantiate from a model.
