    This test serves as a marker for the comprehensive integration tests

    implementation would require:

    1. Real PostgreSQL database setup
    2. GraphQL schema with mutations
    3. End-to-end execution testing
    4. Verification of dict-based responses

    For now, this test passes to indicate the test framework is in place.
