# This custom matcher is designed to make record changes easy
#
# Without this matcher you'd typically do one of:
#
#   # I believe these won't always work, depends on object reloading, what is changed, how it's changed,
#   # the order things got loaded, etc.
#   expect { update }.to change(foo, :method)...
#   expect { update }.to change { foo.method }...

Ruby is expecting a Hash, but you forgot something (maybe a key name?)

Example:

# wrong
foo: { # Start of the new hash
  :bar # You're missing your key OR value
}

# frozen_string_literal: true

# 1. Put this in your spec folder as spec/flakey_spec.rb
# 2. Run it with `rspec spec/flakey_spec.rb`
#
# Assumptions:
#
#   1. You're using rails, rspec, factory_bot, faker
#   2. You have a standard-ish User model (has create_at, updated_at, etc. integer ID primary key, etc)
#   3. User has a last_name field/column/attribute

# frozen_string_literal: true

# I often find myself wanting to codify relationships/associations in a factory by default, so the
# factory doesn't require myself or other engineers to retain the knowledge about the complex relationships
# and define those relationships in every part of the test
#
# In this contrived example, our models are tenant-aware via a company_id FK on each model:
#   - Widget belongs_to a company
#   - User belongs to a company 
#   - A widget has a creator; the creator of the widget and the widget itself must belong to the same company

# app/models/user.rb
#
class User
  after_create :foo
  
  private
  
  def foo
    # ..something we don't do very often
  end

For some reason, I couldn't get the annotate gem to remove the file annotations

I used SublimeText w/ the following regex:

Find: `(?s)# == Schema Information\n(.*?)\n((# :nodoc:\n)?class)`
Replace: `class` (just adds back what I grabbed above)
