end

#data_sets_different?(original_service_checker, compare_key_map) ⇒ Boolean

Precondition: the original checker passed without errors meaning the expected set was present handles both subset < complete and complete > subset checks via two checks.

  • differences in the calculated id set for ‘_id` searches signal differences in the data sets.

  • errors during instantiation signal that a resource in the set wasn’t present. Since the original set was complete, this will only happen if the original set was a subset and the complete set includes more data, meaning that the sets are different. (NOTE: triggers an error rather than a different set of ids because fhirpath like ‘…resolve().id` requires the resource be present to evaluate it)

Returns:

  • (Boolean)
