[chef] Using ChefDK on a CI server?

[Steffen Gebert < >]

Hi,

I try to set up a CI server using Jenkins for our cookbook testing and
finally uploading to Chef server.

Would you recommend to use ChefDK to run test-kitchen, Berkshelf and so
on, or should I use Bundler and respect the gem versions specified in
the Gemfile?

Thanks for your opinion
Steffen
