class_docstr: Test that checks if the multiple card decorators work with @step code.
  - This test adds multiple `test_pathspec_card` cards to a @step
  - Each card will contain taskpathspec
  - CLI Check:
      - List cards and cli will assert multiple cards are present per taskspec using `CliCheck.list_cards`
      - Assert the information about the card using the hash and check if taskspec is present in the data
  - Metadata Check
      - List cards and cli will assert multiple cards are present per taskspec using `MetadataCheck.list_cards`
      - Assert the information about the card using the hash and check if taskspec is present in the data
