I know this is 3 years old and has no activity, but I found your blog post today, and it's pretty useful. There's a mistake though. When you require the gem name:

require 'test_gem'

that is requiring the version of that gem that is installed. You would need to run gem build *.gemspec and gem install *.gem to install the version of your gem with the changes you just made during development. This isn't very useful, as most people don't build and install their gem for every little change. Instead, change that line to this:

require_relative 'lib/test_gem'

and as long as you are using Ruby's gem file structure conventions, it will load the actual files you are working with. This was you can save your files, and run reload! from pry without ever exiting. Here's the relevant sections from my Rakefile for reference (gem name is brewer):

task :console do
  require 'pry'
  require_relative 'lib/brewer'

  def reload!
    files = $LOADED_FEATURES.select { |feat| feat =~ /\/brewer\// }
    files.each { |file| load file }
  end

  ARGV.clear
  Pry.start
end

Other than that, this is cool, and I know I'm going to use it. Thanks.

Edit: This needs to be run from the root of your gem during development, but that's usually where people work anyway.
