Feature: List Functionality
  As a user
  I want to list datasets
  So that I can see what's available

  Scenario: List specific datasets
    When I list datasets "wordnet,schema-org"
    Then the list output should show dataset information
    And the list should show 2 datasets

  Scenario: List empty dataset array
    When I list no datasets
    Then the list should show all registered datasets

  Scenario: Get size category for very large dataset
    When I get size category for 5000 GB
    Then the size category should be "10M<n<100M"

  Scenario: Get size category for extremely large dataset
    When I get size category for 50000 GB
    Then the size category should be "100M<n"

  Scenario: Decompress file that doesn't need decompression
    Given a regular uncompressed file
    When I decompress the file
    Then decompression should succeed without changes

  Scenario: Get dataset info with error
    When I get dataset info for nonexistent dataset
    Then None should be returned from get_dataset_info

  Scenario: Check HF exists with no organization
    When I check HF without organization configured
    Then the check should return false

  Scenario: Check HF exists with authentication error
    When I check HF with auth failure
    Then the check should handle error gracefully
