module Tdc
module Generators
#
# Knows how to resolve attribute values in an instance definition. The attribute value will be replaced
# by the result of invoking the registered resolver.
#
# The resolve_tag class macro is provided for generators to define tag resolution. The test data definition
# YAML file has attribute values than contain a catalog entry tag.
#
# Example:
#
# Suppose a particular instance definition contained { subcomponent: sc_snackers_minis } then a generator
# could resolve the subcomponent tag to the current catalog by defining:
#
# resolve_tag key: :subcomponent, source: "item_master.items"
#
# The register_definition_resolver class macro is provided for generators to define and register their own
# definition resolvers. The test data definition YAML file has attribute values than contain an arbitrary
# value that will typically be replaced by an instance of an object returned by the specified resolver.
