Descriptive messages with basic asserts

What if I told you that it's possible to get helpful failure messages from basic asserts using idiomatic equality == checks? No DSLs in sight.

This is a proof of concept to demonstrate that it's possible... mostly to satisfy my own curiosity. The concepts here could theoretically be expanded to provide a useful extension to existing testing frameworks or perhaps lay a foundation for an entirely new one.

This experiment created with Ruby 3.0.1. Note to self: There's probably a way to do this with TracePoint instead of monkey patching but I couldn't figure out how to get a reference to the passed variable being compared.

Examples:

# frozen_string_literal: true

module Broadcastable
  extend ActiveSupport::Concern

  def prepend_operation(options = {})
    operation = {html: ApplicationController.render(partial: to_partial_path, locals: locals)}
    operation.merge options
  end
