I saw a really great issue in the Rails repo where someone was able to demonstrate a full rails issue without having to recreate an entire application. I thought this was fantastic because I have never setup an example like this before and think it would save a ton of time when iterating on ideas or reproducing issues.

# 1. Add any gems that you may need inline
require "bundler/inline"

gemfile(true) do
  source "https://rubygems.org"

  git_source(:github) { |<em>repo</em>| "https://github.com/#{<em>repo</em>}.git" }

  # Activate the gem you are reporting the issue against.

  gem "sqlite3"
  gem "pry"
end

require "active_record"
require "minitest/autorun"
require "logger"
require "pry"

# This connection will do for database-independent bug reports.
ActiveRecord::Base.establish_connection(adapter: "sqlite3", database: ":memory:")
ActiveRecord::Base.logger = Logger.new(STDOUT)

ActiveRecord::Schema.define do
  create_table :posts, force: true do |<em>t</em>|
    t.string :name
    t.text :description
    t.datetime :routing_start_date
    t.datetime :routing_end_date
  end

end

class Post < ActiveRecord::Base
  has_many :comments
end

class BugTest < Minitest::Test
  def test_association_stuff
    post = Post.create!(name: [])
    post.routing_start_date = DateTime::Infinity

    assert_equal DateTime::Infinity, 
    post.routing_start_date
  end
end
