What's a good tutorial for creating a gem with RSpec? [closed]

Question

I've been searching around for ways to create a gem with RSpec, but haven't found descriptive tutorials.

I started out with Ryan Bates' Making a gem, but I'm looking for a tutorial that discusses creating an acts_as style gem with RSpec.

By acts_as, I mean to say that the gem adds certain methods to an existing class in Rails. Why is this important? Because I've found gem templates like New Gem, got a spec to run but when I try to test an Active Record object it starts choking. I've tried requiring active_record in spec_helper.rb but I must be doing something wrong because it doesn't solve the problem.

When it comes to plugins, I found this Rails Guide. If there's a gem version for that around that'd be awesome.

Thanks guys!

P.S. I love screencasts.

Answer 1

I like using jeweler for starting gems.

to generate a gem skeleton with rspec

jeweler --rspec my-gem-with-rspec

Answer 2

This question should have an answer about Bundler.

As much as I know, Bundler is -maybe- the most popular and used tool for easily creating gem skeletons.

And here is a great tutorial about it:
