Test Runner for Wiki.js Python SDK

This file provides a simple way to test the SDK functionality without needing
a real Wiki.js instance. It uses mocked responses to simulate API interactions.

Usage:
    python test_runner.py

Or import and run specific tests:
    from test_runner import run_all_tests, test_client_creation
    run_all_tests()
