First install the required gems:

gem install octokit awesomeprint rainbow

Then run it to extract all of your open GitHub issues into files (with comments).

ruby my-gh-issues.rb

require 'test_helper'
require 'clearance/testing'

class EmployeesControllerTest < ActionController::TestCase
  
  test "an ASM can not create a user" do
    sign_in
    assert_raise CanCan::AccessDenied do
      post :create, :employee => { :name => 'Feed Store' }
    end

This example is not my real app, but it's modeled pretty closely to it.

My mom schedules a couple hundred employees at a local warehouse. In their system, a worker can earn "points" for being late or missing shifts. Here we have a sort of summary screen for my mom, who may need to follow up with new employees or discipline employees with concerning levels of points.

Questions that arise as I code something like this:

• Which objects deserve presenters?
