Parameters:

  • parent (Fixtury::Definition) —

    the parent definition

  • thing (Fixtury::Dependency, Hash, Array, String, Symbol) —

    the thing to resolve @option thing [Fixtury::Dependency] a dependency will be cloned. @option thing [Hash] a hash with exactly one key will be resolved as { accessor => search }. @option thing [Array] an array with two elements will be resolved as [ accessor, search ]. @option thing [String, Symbol] a string or symbol will be resolved as both the accessor and the search.

Returns:
