"""Phase 2 component test: Wan2.2-Lightning fp8 pipeline + LoRA stacking.
"""Phase 2 component test: Wan2.2 pipeline + LoRA stacking.
Verifies:
- ``Wan22Pipeline`` loads successfully against the fp8 distill path
(exercises the real LightX2V set_config → init_runner flow).
- ``Wan22Pipeline`` loads successfully (exercises the real LightX2V
set_config -> init_runner flow).
- ``load_loras`` / ``unload_loras`` survive with the two user LoRAs at
``/cache/loras/wan22-[HL]-e8.safetensors``.
Requires GPU and a first-run download of both HF repos (base support files
~12 GB, fp8 DIT ~30 GB). If LightX2V isn't installed the test is skipped.
Supports both fp8 and GGUF DIT quantisation. Set the ``DIT_QUANT``
environment variable to switch (default: ``fp8-sgl``).
Run:
DIT_QUANT=gguf-Q4_K_M docker compose exec voice-chat \
python -m tests.component.test_02_wan22_loras
Requires GPU and a first-run download of both HF repos (base support files
~12 GB, DIT size depends on quant — fp8 ~30 GB, GGUF Q4_K_M ~19 GB).
If LightX2V isn't installed the test is skipped.
Run (default fp8):
docker compose exec voice-chat python -m tests.component.test_02_wan22_loras
