I'm writing Chef wrappers around some of the built in OpsWorks cookbooks. I'm using Berkshelf to clone the OpsWorks cookbooks from their github repo.

This is my Berksfile:

```
source 'https://supermarket.getchef.com'

metadata

def opsworks_cookbook(name)
  cookbook name, github: 'aws/opsworks-cookbooks', branch: 'release-chef-11.10', rel: name
end

%w(dependencies scm_helper mod_php5_apache2 ssh_users opsworks_agent_monit
   opsworks_java gem_support opsworks_commons opsworks_initial_setup
   opsworks_nodejs opsworks_aws_flow_ruby
   deploy mysql memcached).each do |cb|
  opsworks_cookbook cb
end

```

My metadata.rb:

```
depends 'deploy'
depends 'mysql'
depends 'memcached'

```

The problem is, when I try to override attributes that depend on the `opsworks` key in the `node` hash, I get a:

```
NoMethodError
-------------
undefined method `[]=' for nil:NilClass

```

OpsWorks has a whole bunch of pre-recipe dependencies that create these keys and do a lot of their setup. I'd like to find a way to either pull in those services and run them against my Kitchen instances or mock them in a way that I can actually test my recipes.

Is there a way to do this?
