add_mocked_facts!() click to toggle source

Add mocked facts based on the metadata present in the module

This means that for some module there are hardcoded mocks, such as stdlib. When stdlib is present in metadata.json, facts like service_provider are mocked and return the correct value according to the OS facts.

A private helper to override_facts

override_facts(base_facts, **overrides) click to toggle source

Override facts

This doesn't use deep_merge because that's highly unpredictable. It can merge nested hashes in place, modifying the original. It's also unable to override true to false.

A deep copy is obtained by using Marshal so it can be modified in place. Then it recursively overrides values. If the result is a hash, it's recursed into.

A typical example:

let(:facts) do

override_facts(super(), os: {'selinux' => {'enabled' => false}})

end

# File lib/voxpupuli/test/facts.rb, line 18
def override_facts(base_facts, **overrides)
  facts = Marshal.load(Marshal.dump(base_facts))
  apply_overrides!(facts, overrides, false)
  facts
end
