Adding Rspec and Guard to a ruby project that isn't backed by Rails

Add Guard to a Ruby workflow

go to your directory

run --> rspec --init
cd into rspec (this is where you create your helper, i.e. bus_spec.rb), or just use touch to place them
cd ..
run --> rspec spec/
run --> bundle init
  add gem 'rspec'
  add gem 'guard-rspec'
run --> bundle install
run --> guard init rspec
run --> guard

#context is for setting up initial conditions
#one use case of descibe is for describing various methods that the class has

after context or describe, see below. This is very powerful so keep reading.

before(:each) do
  @user = User.new(params)
end

OR BETTER (more specific)

let(:user) do
  User.new(params)
end

it "provides gender blah blah blah" do
  expect(user.gender).to eq(m)
end
