Overriding structured facts

[bodgit]

#37 covered how to set custom structured facts but this doesn't seem to work when I want to override an existing nested structured fact.

For example, I want to force $facts['os']['selinux']['enabled'] to be true regardless but it's always false because that's what is now set in the shipped facts, (fairly sure it used to be true or unset in previous facterdb releases so it was working by chance).

      let(:facts) do
        facts.merge({
          os: {
            selinux: {
              enabled: true,
            },
          },
        })
      end

I found there is a deep_merge gem pulled in via Puppet so I tried instead:

      let(:facts) do
        DeepMerge.deep_merge!(facts, {
          os: {
            selinux: {
              enabled: true,
            },
          },
        })
      end

But this gem seems to have odd merge behaviour and won't overwrite existing values.

What's the easiest way to do this?

The approach I took was to create an override_facts helper:
voxpupuli/voxpupuli-test@87d851c

@mcanevet Should this be contributed to rspec-puppet-facts?

[bodgit]

Having something as part of this package would be super useful.

@ekohl this cool be cool, indeed.
