    Integration Tests for the Authorization Server Clients Resource

    This test suite provides comprehensive integration testing for the Authorization Server Clients API
    within the Okta Python SDK. The tests validate real API interactions using VCR for recording
    and replaying HTTP requests/responses.

    API Methods Tested:
    1. list_o_auth2_clients_for_authorization_server() - List OAuth 2.0 clients for an auth server
    2. list_refresh_tokens_for_authorization_server_and_client() - List refresh tokens for a client
    3. get_refresh_token_for_authorization_server_and_client() - Get a specific refresh token
    4. revoke_refresh_token_for_authorization_server_and_client() - Revoke a specific refresh token
    5. revoke_refresh_tokens_for_authorization_server_and_client() - Revoke all refresh tokens for a client

        Test the complete lifecycle of Authorization Server Clients operations

        This test covers:
        - Creating a temporary authorization server
        - Creating a temporary OIDC client application
        - Listing OAuth 2.0 clients for the authorization server
        - Listing refresh tokens for a specific client (may be empty)
        - Getting a specific refresh token (if available)
        - Revoking refresh tokens (if available)
        - Cleaning up temporary resources

        Note: Refresh token operations may return empty results if no tokens exist,
        which is expected behavior in a test environment without interactive OAuth flows.
