Add more tests for Python Client #1779
Description
Is your feature request related to a problem? Please describe.
The current Python client relies solely on auto-generated tests from the OpenAPI generator, which provide only basic sanity checks and do not cover real-world use cases. For example, as shown in PR #1778, missing parameters were not caught by existing tests. We need to add comprehensive tests to ensure correctness and robustness.
