beaker and git modules

Complete newby with beaker-rspec. How would I get a Git repo? Something like this:

hosts.each do |host|
      on host, puppet('module','install','puppetlabs-stdlib'), { :acceptable_exit_codes => [0,1] }
end

But with my own personal module. This is a profile module that I pull with r10k, but I haven't seen anything online or here on the forums on how I would pull an entire control repo or install a Puppetfile and use that to pull all of my modules. **Update:** Apparently this is already on the beaker's Jira board: https://tickets.puppetlabs.com/browse/BKR-21 Read through the comments for Tim Hughes work-around at the bottom
