How do I setup Rspec, Cucumber to test a Gem?

Hi,

my question unwields me as a complete noob - which is okay - but I
apologize for this totally basic question <:)

I’ve bought the PragProg Rspec Book and googled, been reading blogs and
what-have-I-not, but nowhere have I been able to find information
detailing how I setup a BDD environment for testing the construction of
a Gem.

I have a …/gem_folder which I hope eventually will be a Gem to use with
Rails 3 and I really would like to upload it to GitHub with a good test
coverage.

From the Rspec Book I’ve learned that within Rails Apps, I use Cucumber
and WebRat (among others) - but the book does not (or at least Iøve not
been able to discover it) show how to setup the environment, without the
Rails App.

I guess my question could boil down to: how do I create the environment
(folders, files) to test a Gem meant to work with Rails?

So far I have:

…/gem_folder
…/gem_folder/features
…/gem_folder/lib
…/gem_folder/pkg
…/gem_folder/spec

and a few files like Rakefile, Manifest, CHANGELOG, LICENSE - and I’m
able to push to Gemcutter and GitHub

but where in this picture does the Rails App fit in? How do I make sure
that the Gem will work went installed/utilized on Rails App’s

best regards,
Walther

The rspec-rails gem is probably a good example for you to read for
ideas.

I like using jeweler to create the structure of my gems. It is like
Rail’s generators but for gems. Try it out:

gem install jeweler
jeweler my_gem --rspec --cucumber

HTH,

not really - but thanks for offering help <:)

I followed the Rspec Book, railscast’s on the subject and used echoe and
jeweller and had myself a genuine push’able Gem -

but as my question was: how for Pete’s sake am I going to be able to
test Rails Controllers and Rails Models?

(even tried reading the rspec-rails gem as suggested by matt wynne - and
implementing parts from that. I partly see where dchelimsky is going,
but it’s just to complex to me, alas)

  • anyways, I’m on my 4th day on this gem-quest - and about to fold and
    walk away with the knowledge that testing is just a tad out of my league
    <:/

But - thanks a bunch for trying to steer me afloat :slight_smile:
