Test resolution with property

[khamusa]

Add an easy way to test the usage of property: field :public, types.Boolean, property: :is_public

I'll take a stab at this.

how will something like this work?

it { is_expected.to have_a_field(:public).with_property(:is_public) }

I think it should also be capable of matching other options too, like hash_key and metadata.

it { is_expected.to have_a_field(:myThing).with_hash_key(:my_thing).with_metadata(foo: :bar, baz: true) }

Nice! This looks good!
