"""Shared pytest configuration for the backend test suite.
|
|
|
|
Puts the backend root on sys.path (mirrors app launch) and provides a hybrid
|
|
``studio_server`` session fixture for end-to-end tests with two modes:
|
|
external server (``UNSLOTH_E2E_BASE_URL``/``UNSLOTH_E2E_API_KEY``) for fast
|
|
iteration, or a fixture-managed server started/torn down per session for CI.
|
|
Model/variant for the managed mode resolve from ``--unsloth-model`` /
|
|
``--unsloth-gguf-variant``, then env vars, then ``test_studio_api.py`` defaults.
