end

Request the EBS volumes IDs.

Test in-depth using aws_ebs_volume to ensure all volumes are encrypted and have a sensible size.

aws_ebs_volumes.volume_ids.each do |volume_id|
  describe aws_ebs_volume(volume_id) do
    it          { should be_encrypted }
    its('size') { should be > 10 }
    its('iops') { should cmp 100 }
  end
