## 1_intro_to_subject.rb
# RSpec's subject method, both implicitly and explicitly set, is useful for
# declaratively setting up the context of the object under test. If you provide a
# class for your describe block, subject will implicitly be set to a new instance
# of this class (with no arguments passed to the constructor). If you want
# something more complex done, such as setting arguments, you can use the
# explicit subject setter, which takes a block.
describe Person do
  context "born 19 years ago" do
    subject { Person.new(:birthdate => 19.years.ago }
    it { should be_eligible_to_vote }

Here's an example of a rspec test helper that will let you sign in as a given user.
Create spec/support/helpers/authentication.rb with the following:
module Helpers

    PSQL

Magic words:
psql -U postgres
Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
