Hey Brandon,
lebowski-spec is a way to conveniently run specs with rspec that
automatically includes the following Lebowski modules:
Lebowski::Foundation
Lebowski::Foundation::Views
Lebowski::Foundation::Panes
As well, lebowski-spec automatically includes special rspec extensions
I created to help make your scripts more readable. Example:
some_view.should have_value "foo"
Although lebowski-spec is provided, you do not have to use it. You can
use rspec as is or any test automation framework for that matter. If
you do use plain old rspec to run your specs, you are then responsible
for adding the various Lebowski modules; however, using rspec by
itself means you have more flexibility in how you can integrate the
scripts into your CI environment.
I can't speak directly to Maven as it's been a while since I've used
it, but if you use rspec by itself then you can use the rspec plug-ins
to get you moving ahead.
