There is a --dry-run command line switch that will do this for you,
but I've been considering deprecating it because it can't work
consistently with matcher-generated descriptions:
describe RSpec do
it { should be_concise }
end
$ spec rspec_spec.rb
RSpec
should be concise
In this case, the be_concise matcher generates the text "should be
concise" when it is run. If you don't run it, there is no description.
As this approach becomes more and more popular, the --dry-run not only
becomes less useful, it actually becomes somewhat of a frustration.
As for getting a handle on the objects, this is something that is not
really baked into RSpec, but will definitely be baked into rspec-2.0.
Work on this will start later this year (probably not until after the
rspec book is off to print). Goals for it include a very clean
separation of the DSL and the underlying object model and a very
lightweight runner.
So in the short run, your best option is to use --dry-run and
understand that you only get value out of it if you write docstrings
for all of your examples.
