rspec users - Mar 2011 - [HOOKS] spec_helper aware of full test suite being run? After hook to run code after running all specs?

Sorry if multiple postings of this show up.  I had to RTFM a few times
before I figured out how to post correctly.

I use VCR to record interactions, and when the recordings change filenames,
and directory structure, over time, as the test suite evolves, the old
recordings, no longer used, are rarely pruned.

I would like to have the ability to run rspec with an option to check for
unused VCR recordings, and another to both check and delete unused
recordings.

I need a way to know if the full spec suite is being run.  I think this can
be determined with some fancy testing on ARGV.

I can get the full list of recordings like this (or similar):

 FileList["spec/fixtures/vcr/**/*.yml"].reject{|file|File.directory?(file)}

And then prune the list as each recording is used by the spec suite,
afterwards having a list of the recordings that should be deleted.

I need a hook that will run after the complete spec suite is run, before
exiting the process, while still in the context of the thread, and the
variable containing my list of files to delete is still accessible.

Failing that I can write the list to a file, and hook in the deletion in the
rake spec task.  The downside of this is I currently run the test suite with
`bundle exec rspec spec`, and don''t really use the `rake spec` task.

Aside: It would involve some (lots?) of work to get `rake spec` working in
this project.  Currently when I run `rake spec` there is no output at all.
 It appears to load the rails env, and do nothing.  Any one have an idea
about that?

Update: I have fixed rake spec.  Someone else on the team had removed
the gem dependency from the development group in the Gemfile.  Once
added back rake spec worked fine.

Some additional data:
rspec 2.5.1
rspec-rails 2.5.1
rails 3.0.4
ruby 1.9.2p0
rake 0.8.7

I have gotten all of this working now with the exception of a way to
hook some code to be run after finishing all specs while still in the
same thread.  When I run Rake::Task["spec"].invoke within another rake
task the list of VCR cassettes that have been ''touched'' by the
tests
is not retained after the invoke method executes.  I''ve tried storing
it in a class instance variable @@file_list, as well as a global ruby
var $file_list, with no dice.

I think the only option to persist the list of file is now to write
the file list to a yaml, and then pull it back out. :(

I have implemented a full solution.  Had to persist the list of unused VCR 
cassettes to the file system.
Cheers!
It would be still be cool if there was an after hook on rspec, as there is 
on capistrano!

Wow!  That''s perfect, I think.  I''ll have to play around with
it and make
sure the after suite can be made to only run code if the entire suite has 
been run, but it looks promising!

The before and after :suite hooks work for running code before and after 
rspec runs all the tests specified, but I need it to explicitly *not run* when 
anything less than every single spec is being run.  In other words is we are 
running rspec spec or rake spec I need this before and after :suite hooks to 
run (to clean-up VCR cassettes).  If we are not running the full suite, then 
it would mistakenly delete the VCR cassettes that were not used by the spec 
run.

So I need it to not run the before and after :suite code if running, for 
example, rake spec:models or rspec spec/controllers.  I am not sure if 
rspec, or spec helper is aware of the full test suite being run.  ARGV
won''t
work because when rake spec runs it executes rspec with every individual 
spec''s path, so there is no way to tell from ARGV if it is the full
suite,
without getting really hacky.

You could make your own task that depends on "spec":

task :task_to_run_all_spec_and_do_something_with_vcr => :spec do
  # my VCR code
end

Obviously, this wouldn''t work with "rspec spec"
