Adds ‘Before` and `After` cucumber hooks for the named tags that will cause a VCR cassette to be used for scenarios with matching tags.

Parameters:

  • tag_names (Array<String>) —

    the cucumber scenario tags

  • options ((optional) Hash) —

    the cassette options. Specify ‘:use_scenario_name => true` to automatically name the cassette according to the scenario name.
